Hello, I have a problem with m2eclipse (0.10.0) together with eclipse galileo (Build id: 20090920-1017).

I always get the error message:"Eclipse is running in a JRE, but a JDK is required". I have tried several things, but nothing works. The error message is still there. Here are the things I have tried:

  • In Window>Preferences>Java>Installed JREs I checked JDK1.6.0_20. DOES NOT WORK

  • In Window>Preferences>Java>Installed JREs I removed all JREs. Only the checked JDK1.6.0_20 is still there. DOES NOT WORK

  • In Window>Preferences>Java>Installed JREs>Execution Environments I choosed JavaSE-1.6 and checked JDK1.6.0_20[perfect match]. DOES NOT WORK.

  • In Preferences of the eclipse desktop start icon I added the -vm parameter (C:\Programme\eclipse_galileo\eclipse\eclipse.exe -vm C:\Programme\Java\jdk1.6.0_20\bin). DOES NOT WORK.

  • I added the clean parameter (C:\Programme\eclipse_galileo\eclipse\eclipse.exe -vm C:\Programme\Java\jdk1.6.0_20\bin -clean). DOES NOT WORK.

  • I added the -vm parameter to the eclipse.ini file with a carriage return after -vm and C:/Programme/Java/jdk1.6.0_20/bin/javaw.exe in a new line. DOES NOT WORK.

  • After doing all these things I removed the m2eclipse plugin and installed it once again. DOES NOT WORK.

New ideas I have tried:

  • In Preferences of the eclipse desktop start icon I put the executable at the end (C:\Programme\eclipse_galileo\eclipse\eclipse.exe -vm C:\Programme\Java\jdk1.6.0_20\bin\javaw.exe). DOES NOT WORK.

  • I changed in eclipse.ini the slashes to backslashes. DOES NOT WORK.

Here is my eclipse.ini file:

-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
org.eclipse.epp.package.jee.product
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vm
C:\Programme\Java\jdk1.6.0_20\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m

Is anyone out there who have other ideas? Any help is appreciated.

Thank You very much. GernoK
