When I try to run a new, blank android project in the latest eclipse SDK a window pops up that says "configure gnu.io.rxtx.properties". (It's the one with 128 check boxes representing 128 serial ports)
When I select some ports and click save, an IOException appears in the console window and nothing else happens.
The project will not run. The window will not go away. How can I fix this problem?
Silly mistake, for some reason 'configure' was set to run and not my project.
Right-click, run as, android. solved.

I just installed Luna. I imported 3 projects all went well for a while.
Then I restarted eclipse and now it shows only two projects. I tried to import the missing project, but it says it already exists in the workspace.
I closed all other projects and pressed Ctrl+Shift+T to see if it still shows up the types from that invisible project. Yes, it shows files from that invisible project. I opened one of the files and selected Show In Project Explorer. Nothing happens.
Also, in the code when I press . after an String object, nothing shows up.
Seems to be strange. Any help?
Also, if I can do fresh import of all projects, that would help too. But again, I don't know why context assist is not working. I can try importing everything afresh. For this, what are all the eclipse related folders / files I need to remove?
Edit
this helped me with workingset / missing projects. But when I press . after an object, nothing comes up.
For others benefit, it has to do with Working sets. You can click Down arrow in Project Explorer and select "Edit Active Working Set". In the window, on the left hand side, you can see your non-visible projects and move it to right hand side to make them show up under active working set. HTH.
Regarding the problem where Eclipse says it "already exists in the workspace": I recently had a similar problem and I fixed it by unchecking the box that says "copy projects into workspace" and then hit refresh and it should work.
Just fixed this issue by clicking 'Deselect working set' ( under dropdown in project explorer ). For me, 'edit Active working set' was disabled to start with.
It sounds like the projects exists on the file system in the workspace directory, but the actual project got deleted or never imported in the eclipse workspace. Take a look at the workspace directory, all three projects should be there. You can delete the "missing" project from the file system and reimport it again.
There is no syntax highlighting in java files in my eclipse..This happened all of a sudden..Not sure why..
This is how it is looking now..
As mentioned in other posts..i tried to change the color from preferences window and there is nothing when i type java..something really messed up...
AAny suggestions..
Update:
It seems Java plugin is not installed..as per the below screeenshot
And when i try to install java plugin it says new version is already installed as per the below screenshot
Closing the file's tab and re-opening it fixed it for me.
(I actually closed all the tabs...)
I faced the same issue all of a sudden after a commit/update project operation.
The point is, default editor of Eclipse has changed somehow and we have to set it back to normal.
Try the below method,
1. Goto Windows -> Click Preferences
2. From the Preferences window goto General -> Editors -> Click File Associations
3. You can choose the default editor for *.java files here
When I first opened Preferences, 'Text editor' was set as the default editor for .java files and then I changed it back to 'Java Editor'.
Now it works perfectly fine.
You probably have a corrupt installation or you have recently installed a corrupt plugin.
The following steps might help.
In your Install window,
view your "already installed" plugins.
select the "Installation History" tab.
select a previous stable configuration
Click the "Revert" button
TLDR; open another workspace, then come back to the original workspace.
Ok this is odd, but for me, all the highlighting suddenly went away for Java files. I explored all of these ideas here, with no effect. I created a new workspace, planning to move everything to it. I realized that can be a pain to move many projects over, so I went back into the original workspace to look at some settings, and poof - the highlighting was working again.
I have one java class file like a text editor.
I tried following,
Select the respective java class file from eclipse.
Right click on the file and mouse hover on "Open with".
Select java editor.
Now its works.
My Eclipse installation has been giving me greif today. After corrupting my Android project to where it would not build any more I was forced to reinstall both eclipse and re-create my project from Scratch.
However, eclipse is still acting oddly. When I press the green Run button in the tool bar quite often it appears to do nothing. No dialog, no progress indicators, no output on the console. If I leave it for a bit and/or hammer the run button constantly, eventually it runs.
What is going on. Have I ticked a 'Run in Background' check box somewhere by mistake. If and even if not, how can I re-configure eclipse to be just a little more responsive again.
EDIT: Turns out in the project settings Eclipse had enabled XML validation for every type of check, this has sped things up a little. However, it's still far from as it was when working well. My guess is there are a number of esoteric lesser used settings enabled somehow. I would still like to know how not to have the Run progress in the background.
Check if disabling Project > Build Automatically and optimizing memory settings in eclipse.ini works.
I have the same problem, sometimes it works and sometimes not. My solution when it happens just click right button on your project in Package Explorer -> Run As -> Android application.
I have been trying to change my Java console color but the run/debug preferences I have set does not seem to work. I have installed the "Eclipse Color Themes" and "Eclipse Chrome" plugins and they work great.
I tried changing that setting on an older version and it worked.
Perhaps a plugin is causing this issue. You could remove them one by one until it works again.
Or perhaps it's a bug with 4.2. Try a previous version.
Or check the bug repository: https://bugs.eclipse.org/bugs/
Changes for me didn't actually take place until I ran a program, then the background color updated.
In preference (clicking on "Eclipse" on mac, "Window" on PC or Linux) section, search for "console". Under "Build/console", set the colours you wish to apply. Restart Eclipse, and build your project. You should see your preferred colour scheme in dark mode while the console is displaying the output of the compilation process.
Settings under "Run/Debug" becomes active whenever you hit the run/debug project and not when you build it. So you may wish to keep the same settings for both "Build" and "Run/Debug" options.
The GUI for managing plugins in Eclipse got a bit of an overhaul in version 3.4.0.
This GUI is accessed via the "Software Updates..." option in the Help menu.
The option to remove the selected Mylyn plugin is greyed out. In fact, this is true of virtually every installed plugin. I know that the Mylyn plugins are optional, so why amn't I provided with an option to remove them?
The following text is quoted from the Eclipse help docs:
The Uninstall wizard allows you to review and uninstall items in your configuration. This wizard is shown when you select items and press Uninstall... from the Installed Software page. To uninstall software from your system:
Click Help > About and then click Installation Details... to open a dialog showing pages that provide more detail about your installation.
Click the Installed Software tab to see a list of the software items that you have installed into your system.
Select the items that you wish to uninstall.
Click Uninstall...
The Uninstall Details page will show you a list of the items that will be uninstalled. Expanding each item will show what additional items (if any) will be uninstalled as a result of your choice.
If you change your mind about which items should be uninstalled, you may click Back to see a checkmark list of the items you selected before. You may check and uncheck different items in the list, and click Next when you are ready to continue.
Click Finish to start the uninstall.
Once all of the software is uninstalled successfully, you will be prompted to restart for the Workbench. Click Yes when asked to exit and restart the Workbench for the changes to take effect.
And just to update it for Helios - Eclipse 3.6
Help->Install New Software at the bottom of dialog there is link What is already installed once you click on that you will get list of installed plugins and Uninstal... button
eclipse 3.5(Galieo)
Help>> Install New Software >> Already Installed Plugins >> select Plugins >> Uninstall works charm.
There are distributions of Eclipse that come packaged with certain plugins that can't be mix-and-matched. That is the case with Mylyn, that went from a student's thesis project to an integral part of Eclipse. If you want to actually get rid of Mylyn, you may want to install Eclipse classic instead of the distribution you have, and then install the stuff you need.
The standard Eclipse distributions come with Myln.
BTW, Eclipser 3.5 completely changes all these screens :(
If you are using Windows, make sure you are running Eclipse as administrator. Without administrator privileges, some options may be grayed-out in "Installed Software".
In eclipse Helios (version 3.6), to uninstall a plugin:
Go to Help->Install New Software...
Click on "What is already installed?" link at the bottom right side of the dialog
In the Installed Software tab choose the software you want to uninstall
Click on the "Uninstall..." button at the bottom
Click 'Finish' on the Uninstall Details dialog
Observe the 'Uninstalling Software %' status at the bottom status bar of eclipse
Click 'Restart Now' when prompted to do so.
Eclipse restarts. Choose the workspace. Now when you go again to the Installed Software window , you do not find the uninstalled software.
In Eclipse 3.6 Helios, the interface has changed again. Go to "About Eclipse", and then click the "Installation Details" button in the about box.
While Help → About Eclipse IDE [or wherever it was in the past or will be in the future] → Installation Details → Installed Software → Uninstall... is the official and preferred way there are features/plugins the latter button of which is disabled.
Remember also that there aren't only plugins but features too. In my case I wanted to remove Mylyn and Wild Web Developer from a rather fresh Eclipse IDE for Enterprise Java and Web Developers package. I did the following.
But first a:
DISCLAIMER
Enter ECLIPSE_HOME at your own risk. Mistakes like typos might be in the following, too. I take no responsibility for whatsoever.
Created the directories features.DISABLED and plugins.DISABLED in Eclipse's home dir.
Moved *mylyn* from ECLIPSE_HOME/features to ECLIPSE_HOME/features.DISABLED
Moved *wildwebdeveloper* from ECLIPSE_HOME/features to ECLIPSE_HOME/features.DISABLED
Moved *mylyn* from ECLIPSE_HOME/plugins to ECLIPSE_HOME/plugins.DISABLED
Moved *wildwebdeveloper* from ECLIPSE_HOME/plugins to ECLIPSE_HOME/plugins.DISABLED
After starting Eclipse there were about a dozen "not found" errors in Eclipse's Error Log view. If you double-click on each of them you can see which dependency plugin JAR(s) haven't been found.
Set the Error Log view's filter to just display errors and warnings.
Moved the dependency plugin *.jars mentioned in the errors from ECLIPSE_HOME/plugins.DISABLED back to ECLIPSE_HOME/plugins one by one (with Eclipse restart after each) until no "not found" error appeared in the view any longer. It were nine *mylyn*.jars in the end.:
*.mylyn.commons.core_*
*.mylyn.commons.net_*
*.mylyn.commons.notifications.core_*
*.mylyn.commons.notifications.ui_*
*.mylyn.commons.screenshots.ui_*
*.mylyn.commons.ui_*
*.mylyn.commons.workbench_*
*.mylyn.commons.wikitext.markdown_*
*.mylyn.commons.wikitext.*
Note that this applies to a rather fresh Eclipse 2021-03 (4.19.0) installation. It might be different from one – even patch – version to the other.
Furthermore:
Keep Eclipse's Error Log view open for a while. The underlying OSGi activates bundles (plugins) on the fly if they are referenced from an other bundle (plugin) for the first time. And if one isn't there then...
Check the Error Log view especially after installing new features/plugins. They might rely on plugins/JARs you moved to .DISABLED. If that's the case move the according JAR(s) back to ECLIPSE_HOME/plugins and/or ECLIPSE_HOME/features.
If something doesn't work as it did in the past once in the future remember what you did and ... → Error Log view.
I'm running (a relatively fresh copy of) 3.4.1. I was able to select the same plug-in shown in your screen shot (Mylyn Bridge: Java Development) to get an enabled "Uninstall..." button. I'd suggest getting the latest updates and trying again.
It sure looks like there's no way to do this.
I just had exactly this problem with a fresh download of the Eclipse Java IDE (Ganymede SR2). I didn't want Mylyn, but I didn't want "Eclipse Classic", either, because the download was twice the size, I presume because it includes source.
The apparent solution was to update everything and restart Eclipse, after which the "Uninstall..." button became enabled for the Mylyn plugins. Unfortunately, this only uninstalled the most recent, updated version (3.0.11 IIRC), reverting to the un-uninstallable 3.0.5.
I just don't know what the hell these Eclipse developers are thinking! Removing plug-ins from Eclipse became a pain in the ass since Helios!
I hear you pal... I just went through the whole day trying to figure out as no one seems to give an straight answer like "do this, that, done."
Man I'd rather be programming instead....
Found, in the middle of my evening that it is possible to uninstall pretty much everything. The issue is that the damn thing is hidden in the "HELP->ABOUT". Who would guess after going over and over through the "Help->Install New Software" or "Help->Check for updates" and never finding anything like "remove" or "reinstall" or "force reinstall".
Seriouly, I'd rather go back to 1990 when we had Microsoft, Borland and Watcom.. you picked your platform and you'd be with 1/3 of the world of developers with you.. ok, perhaps Watcom didn't hit that mark but you get the point.
So... to uninstall any plugin from Eclipse Helios (Service Release 1) or Springsource 3.5.2 (or 3.6.1 I 'm using), do this:
close all your projects (just to be on the safe side);
Hit menu "HELP-->ABOUT" (yeah.. help, about);
Hit "Installation Details" button and you get the list with all plugins;
Click on the one you want to remove; hit uninstall;
If want to remove more than one, just apply the change without restart;
Goto to 4) as needed
Finally, restart Eclipse and reinstall what you need !
It was hard to find, but it worked very well for me.
