While building with ant, I am getting the following error:
java.io.IOException: Cannot run program \"D:\\Tools\\Java\\jdk1.6.0_12\\jre\\bin\\java.exe\
I'm encountering the same issue(at least the error and description). All SO search and google search points to the bug stated at https://bugs.eclipse.org/bugs/show_bug.cgi?id=327193 and http://www.eclipse.org/forums/index.php?t=rview&goto=494195&th=156565.
But when I try a simple change to launch the application, it works.
Previously, I'm using the way of "right click -> debug -> Java application" to start the application, and got the error.
I changed the way to manually add a debug configuration in menu "Debug -> Configurations", specify the class you want. Then click 'Debug' in the debug configurations dialog. It works...
Note that I'm using a customized IDE based on Eclipse 3.6.2.
