问题
I seem to have an incorrectly specified JAVA_HOME variable. I can get around it for many things but now I am seem to be stuck. I am trying to use the Google App Engine and upload an application.
When I do so I get the error that the error:
cannot find javac executable based on java.home, tried "C:\Program Files\Java\jre6\bin\javac.exe" and "C:\Program Files\Java\bin\javac.exe"
I don't understand why it is looking there, doing echo %JAVA_HOME% gives me:
C:\Program Files\Java\jdk1.6.0_14
Which is where Java actually is. I am thinking my best hope might be to just put Java where it is looking for it - can you think of anything better.
回答1:
Looks like it's possibly a bug:

There are lots of suggested workarounds/solutions, but comment #24 in the bug entry seems promising:
The problem is that GAE plugin for Eclipse is default configured with a JRE instead of a JDK.
To change this, do the following:
Preferences > Java > Installed JRE's > Add... For 'JRE Type' select 'Standard VM' > Next > Directory: select your JDK directory (instead of JRE) (in my case: C:\Program Files\Java\jdk1.6.0_16 ), press OK.
Now, you are back at 'Installed JRE's', select the JDK here also.

Double check for any typo in the JAVA_HOME path.

Or simply add "C:\Program Files\Java\jdk1.6.0_14\bin" to your %PATH%
