I'm working on a java project on eclipse. It used to work when i press Run As Eclipse Application. And now it suddenly stopped working:
The only thing i did since the last time it worked is uninstalling and installing different java and jdk versions. Currently i have these 3 in C:\Program Files\Java:
- jre7
- jre1.8.0_20
- jdk1.8.0_20
I don't know what's the 2nd one. I can't find it in "Programs and Features".
In the path variable i have:
C:\Program Files\Java\jre7\bin;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v6.5\bin;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v6.5\libnvvp;C:\Python27\Lib\site-packages\PyQt4;C:\Python27;C:\Python27\Scripts;C:\OpenSSH\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files\nodejs\;C:\Downloads\Android\adt-bundle-windows-x86_64-20140702\sdk\tools
And here's some of the log when i hit "Yes, in an editor" on the error message:

Why is this happening?
Should i post additional information so the problem could be identified?
edit:
I found the following warning in the project:
The JRE container on the classpath is not a perfect match to the 'JavaSE-1.6' execution environment MANIFEST.MF /JDTCommentsV2/META-INF line 11 Plug-in Problem
corresponding to this line in MANIFEST.MF:
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
edit:
I fixed that by: right-click -> Quick Fix
but now i got another error:
Build path specifies execution environment JavaSE-1.6. There are no JREs installed in the workspace that are strictly compatible with this environment.
Solutions here and here suggest choosing Workspace default JRE in Project->Properties -> Add Library -> JRE System Library. This brings back the:
The JRE container on the classpath is not a perfect match to the 'JavaSE-1.6' execution environment MANIFEST.MF /JDTCommentsV2/META-INF line 11 Plug-in Problem
edit:
i changed the workspace location (put it on desktop) and now it works. But i need the original path (because it's a shared folder in dropbox...). Any ideas?
