I am not expert in linux but can find my way around it most of the time. I have install Eclipse IDE for Debian 10 and tried to create a desktop entry. This is what I did: Created a eclipse.desktop file in ~/.local/share/applications directory. These are the contents of the file: [Desktop Entry] Name=Eclipse Java IDE Comment=Eclipse Java IDE Type=Application Encoding=UTF-8 Exec=/home/testaccount/eclipse/cpp-2020-03/eclipse/eclipse Icon=/home/testaccount/eclipse/cpp-2020-03/eclipse/icon.xpm Categories=GNOME;Application;Development; Terminal=false StartupNotify=true Saved filed and gave exec permission with chmod +x ~/.local/share/applications/eclipse.desktop. I rebooted my Debian VM already and I do not have the icon still. I currently created a soft link to it in the meantime. Not sure why the desktop entry is not working yet, I am not sure what I am missing. Thank you.

When I open my .java file in vim, I could see a couple of lines prefixed with one / more ^I characters. It looks like tabs in Eclipse that has got converted into ^I. I would like to replace a single ^I into spaces with 4 characters. E.g ^I^I^I^IList rulePackagesHistory = result.getHistory(); How can do that in vim editor?

I run eclipse on linux mint. The installation uses flatpak as an envelope for execution. The exact command is: /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=eclipse --file-forwarding org.eclipse.Java I want to pass the workspace path to eclipse and after googling, found that eclipse can take an argument specifying the workspace. Specifically, it is the -data argument, which takes a path to the workspace. So, I tried: /usr/bin/flatpak run --branch=stable --arch=x86_64 --command="eclipse -data " --file-forwarding org.eclipse.Java I quoted the whole command because when left out the quotes, flatpak complained that it did not recognize the -data flag. However, now I get the following error: bwrap: execvp eclipse -data /home/dan/eclipse-workspace-minion: No such file or directory I am guessing that quoting eclipse interferes with flatpak's search for the eclipse executable. (BTW: I checked and the directory /home/dan/eclipse-workspace-minion exists.) Can anyone advise me how to pass the -data argument to eclipse when it is executed through flatpak?

I want to open eclipse through terminal and i am able to do it, but when when eclipse starts it asks for the workspace directory attached the screenshot,and then there i have to specify it, i dont want this. As i pass the **eclipse** command in the terminal, i want to pass the workspace directory along with the eclipse command followed by **OK** as prompt ask for it. Thanks in advance.

I would like to install the latest version of Renesas' e2studio on my up-to-date Fedora 39 machine but I keep getting the following error:

I have tried to find a solution by searching the web but have not succeeded so far. Can anyone here help me to get this resolved?

I tried to compile the Hello World program in C, inside Eclipse PTP, but it gives me an error related to mpi.h. I have included /usr/local/include and /usr/local/lib in my paths, and also tried running a search with find / -name mpi.h. I still get a *No such file or directory* error. I tried to install mpich2, but still couldn't find mpi.h. Also: - There is no folder inside the include directory, why is that? - I can find mpicc at /usr/bin/mpicc The same problem occurs when trying to compile the project as C++ code. What should I do?

I'm using Ubuntu 22.04 and Eclipse IDE (09.22). Every time I show the tooltip (for javadocs or so) it's just empty. I've seen people talking about similar problem and one of these solutions is to install gnome-color-chooser but I'm worried color-chooser is not right for jammy (Ubuntu 22.04) : I tried to install the deb but there are too many dependencies to be installed (who need dependencies on their own). Does anyone have the same issue? or know how to solve it? thank you.

I am developing a C++ application that requires root privilege. I am working under Eclipse and I would like to be able to launch/debug from it. I know I could start Eclipse as a root, but I am looking for other options, such as somehow requesting the elevation in the launch configurations. Any idea ? ---------- Note that my question is not about how to discourage myself to debug with root privilege.

When I start Thunderbird or the IDE 'Eclipse', there are no icons in the menu entries. Several solutions found on the Internet suggest things like setting a specific dconf-value, but with my installation (Arch) this is not possible: % gsettings set org.gnome.desktop.interface menus-have-icons true No such key 'menus-have-icons' So what is the current way for enabling these icons?

When installing "**Jboss tools 4.24.0 Final**" in Eclipse, the following error message appears: > Warning: You are installing software that contains unsigned content. > The authenticity or validity of this software cannot be established. > Do you want to continue with the installation? By clicking on "**Install anywhere**", the installation is aborted and "**Jboss tools**" is not installed. Does anyone have an idea on the source of this error ? Thanks.

I am using zorin os 16 pro. I am using eclipse in windows machine for few months. It works fine in windows. But problem in zorin os. I download eclipse from [this](https://flathub.org/apps/details/org.eclipse.Java) site. All things are fine except window builder. The drag & drop, border is not correct. Like this image I have installed WindowBuilder 1.9.8 and WindowBuilder Nightly Build 1.9.9. Is there any solution out there? Need help. I have googled but not find the solution yet. Anyways, I love eclipse because I can customize all the code generated. Is there any alternative like eclipse? So that I can customize all codes include auto generated code? I have tried netbeans and intellij but I can not customize generated code. Sorry for my bad english. Thanks to all. I have tried saveral ways like change layout, drag and drop etc.

On RHEL 8 I just installed Eclipse 2021-09 from the standalone install archive eclipse-jee-2021-09-R-linux-gtk-x86_64.tar.gz. When running it, the application opens up with the default window, but then shows an error dialog with the following message: > Unhandled event loop exception No more handles because there is no underlying browser available. Please ensure that WebKit with its GTK 3.x bindings is installed (WebKit2 API level is preferred). Additionally, please note that GTK4 does not currently have Browser support. I guess some libraries are missing. For another X11 application I had already run yum install gtk3-devel gtk2-devel but Eclipse might need more. What do I have install to get Eclipse running?

I've followed this question to add eclipse to the path (using ln -s to make a link to /usr/local/bin/eclipse from home download), and when i type

eclipse

I get /usr/local/bin/eclipse, but when I type

into the terminal I get a snap message saying:

'eclipse' not found, but can be installed with: sudo snap install eclipse

I explicitly went the route of downloading the tar file from Eclipse's website to avoid snap. Is this an issue with snap trying to "overide the PATH" or have I not setup eclipse into the path correctly?

Mint auto-classifies applications into categories in the start menu. I use this classification to navigate apps more easily. Recently I have installed Eclipse IDE and Mint failed to classify it as "programming", instead labeling it as "other". How do I manually classify this application as "programming"?

I just installed the tomcat 10.0.12 using below command

$ mkdir /opt/tomcat

$ cd /opt/tomcat

sudo wget https://dlcdn.apache.org/tomcat/tomcat-10/v10.0.12/bin/apache-tomcat-10.0.12.tar.gz 

$ tar xvzf apache-tomcat-8.5.65.tar.gz

$ nano ~/.bashrc
and set the environment variabels in it which are
export JAVA_HOME=/usr/lib/jvm/jdk-17
export CATALINA_HOME=/opt/tomcat/apache-tomcat-10.0.12
saved the changes

$ . ~/.bashrc

$ $CATALINA_HOME/bin/startup.sh

then i runned http://127.0.0.1:8080 in browser it worked perfectly fine for me but when i checked that application for which i installed the tomcat 10.0.12 it said for now its not supported to use tomcat i have to install tomcat 10.0.10 so i unistalled tomcat using below command

sudo rm -rf /opt/tomcat

and installed tomcat 10.0.10 by making few changes in above code but when i runned http://127.0.0.1:8080 again the page shown me this instead of showing me this please ignore 8.5.05 cause i downloaded this image from another website which was providing tutorial to insatll tomcat on linux i think tomcat didn't uninstall completely and still running what should i do please tell me

Today i downloaded the latest installer(eclipse-inst-linux64.tar.gz) of eclipse from the official website and i installed in my system. now i want to create a shortcut to launch the program. how can i do that ? if i double click on the eclipse file which is selected as the screenshot i am able to launch the program, someone help me to create a shortcut

I'm running Eclipse and I detached some of the windows. Now I have 4 windows linked to Eclipse. What I need is to be able to identify each individual window and be able to control it. If I run tools like: xprop, xwininfo, or wmctrl -l I can retrieve the WM_CLASS and WM_NAME for the main window but I can't get them for the other 3 child windows. How can I retrieve the WM_NAME and WM_ROLE for all 4 windows?

I run gnome shell 3.6 and Eclipse 4.2. I installed Eclipse manually, in my /opt directory, because the Ubuntu package for Eclipse is very outdated. I've created a .desktop file for it, and placed in in ~/.local/share/applications. It looks like this: [Desktop Entry] Type=Application Name=Eclipse Comment=Eclipse Integrated Development Environment Icon=/opt/eclipse-4.2.1/icon.xpm Exec=/opt/eclipse-4.2.1/eclipse Terminal=false Categories=Development;IDE;Java; I can run Eclipse from the Activities menu; if I hit the super menu and type in "Eclipse" and run it, it starts just fine, and shows up in my launcher/sidebar/dock/whatever it's called. But if I right-click on its icon, there is no "Add to favorites" option. (I notice this is also the case if I run some very old programs, like xeyes and xcalc. it's amazing these are still distributed!) So what is it about a program that determines whether or not the "Add to favorites" option is available? if I knew and understood that, maybe it'd set me on the right path to fixing this Eclipse problem.

I am on **Debian** Buster, **Mate Desktop** theme Menta, OpenJdk 11.0.9.1, **eclipse 2020-06**. My scroll bar sliders in eclipse are huge. I tried resizing them by a custom gtk-3 css file but this did only change the bar itself but not the buttons. *gedit* does apply the css settings. See bewlo: It does not matter if **theming in eclipse** is on or off (I restarted) or the used eclipse theme. I read about the setting and tried changing -Dswt.enable.themedScrollBar=false / true in eclipse.ini, didn't change a thing. **gtk-3 css** The ~/.config/gtk-3.0/gtk.css I tried. Pretty much the default values from GTKTheme

css
    scrollbar slider {
      /* Size of the slider */
      min-width: 6px;
      min-height: 6px;
      border-radius: 6px;
      -GtkRange-slider-width: 6;
      -GtkRange-stepper-size: 6;
      -GtkRange-stepper-spacing: 0;
      -GtkRange-trough-border: 1;
      -GtkRange-arrow-displacement-x: 0;
      -GtkRange-arrow-displacement-y: 0;
      -GtkRange-activate-slider: FALSE;
      -GtkRange-trough-side-detrails: FALSE;
    }

**gtk-2 gtkrc** I tried setting ~/.config/gtk-2.0/gtkrc

css
    style "scroll"
    {
     GtkScrollbar::slider-width = 6
    }
    class "*" style "scroll"

**Side note:** It looks even worse using the dark eclipse theme as the slider colour does not change.
