The maven project I was building required the use of the 1.6 JDK. The path to my JDK http://maven.40175.n5.nabble.com/Unable-to-locate-the-Javac-Compiler-Problem-td133804.html 1.6 can be entered on the hudson 'configure system' screen, but it isn't possible to choose this JDK in the project config (and if you don't specify a JDK here the default system JDK gets used). I eventually unable to discovered that the option to choose JDK only appears if two or more JDKs are entered in 'configure system' It should be possible to override the default JDK without having to specify more than one JDK.

If you had no JDKs and added one this would work correctly; all projects would then use the configured JDK. However, if you have multiple JDKs and some were configured with "(Default)", then moving down to one JDK does not switch those projects. They continue to use java from path until you click Save on their config screen, which will switch it over (even though no JDK selector appears). So the question is: show the selection box when only one JDK is configured (pick "(Default)" vs that one) or fix things so moving down to one JDK switches all "(Default)" projects to that one JDK.

In most cases you can change the location of your Java installation by setting the JAVA_HOME environment variable. Both JAVA_HOME and eclipse -vm option are set, it occurred after the m2eclipse installed long time ago. Today it raised suddenly. However the error message may be confused. The tools.jar doesn't locate in C:\Program Files\Java\jre6\..\lib\tools.jar. my JDK directory is liked this: ├─jdk1.6.0_17 │ ├─bin │ ├─demo ........................................ │ ├─jre │ │ ├─bin │ │ │ ├─client │ │ │ ├─new_plugin │ │ │ └─server │ │ └─lib ......................................... │ ├─lib ......................................... ├─jre6 │ ├─bin │ │ ├─client │ │ └─new_plugin │ └─lib ......................................... └─lib (doesn't exist) I create the lib and put tools.jar in that jre6/../lib, it works.
