Need solution for this problem? (setting classpath programatically for a
java project)
I am creating plugin which will create a java project and extract some
code in that. then i have
to build that code. for that i need to set two jar filenames in classpath
which are under a location.
how to set that pls. provide snippet..
/*************************************
IClasspathEntry[] newEntries = new IClasspathEntry[entries.length + 2];
System.arraycopy(entries, 0, newEntries, 0, entries.length);
newEntries[entries.length] = JavaCore.newLibraryEntry(new
Path(jdoJarName), null, null);
newEntries[entries.length + 1] = JavaCore.newLibraryEntry(new
Path(pjrtJarName), null, null);
// newEntries[entries.length] =
JavaCore.newLibraryEntry(new Path(jdoJarName), null, null);
// newEntries[entries.length + 1] =
JavaCore.newLibraryEntry(new Path(pjrtJarName), null, null);
if (!jp.hasClasspathCycle(newEntries)) {
jp.setRawClasspath(newEntries, new NullProgressMonitor());
}

The path 'D:eclipse/RC2/plugins/com.abc.ide.eclipse/lib/jdo.jar' looks
suspicious to me.
Shouldn't it be: 'D/:eclipse/RC2/plugins/com.abc.ide.eclipse/lib/jdo.jar' ?
(note the leading /)
