Hello everybody, I begun to set up eclipse, to begin programming, and everything was ok until this problem that's stuck me. This error : Code: 09/02/11 22:23:39 CET: Eclipse is running in a JRE, but a JDK is required Some Maven plugins may not work when importing projects or updating source folders. You'll certainly ask me if i put the -vm options into the eclipse ini file ... and yes I did. My eclipse.ini Code: -startup plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810 -product org.eclipse.epp.package.java.product --launcher.defaultAction openFile --launcher.XXMaxPermSize 256M -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -Xms40m -Xmx384m -vm C:\Program Files\Java\jdk1.6.0_23\bin\javaw.exe I hope someone will be able to help me, i think just for fun my first plugin will be an /unstuck command n0way P.S : i'm sorry if i did some english mistake. --- merged: Feb 10, 2011 7:16 AM --- I found the problem, I changed my eclipse.ini by that : Code: -startup plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810 -product org.eclipse.epp.package.java.product --launcher.defaultAction openFile --launcher.XXMaxPermSize 256M -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vm C:\Progra~1\Java\jdk1.6.0_23\jre\bin\javaw.exe --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -Xms40m -Xmx384m
