I just ran the build using the Eclipse compiler and it worked fine.
Here's
what I did.
1. Check out all of the code from the classlib trunk [1] down. You need

2. From the 'trunk' folder, run 'ant fetch-depends', which downloads all

Ant can set bootclasspath for compiler or any other subsequent jvm
calls. But it will use original vm.
So if your JAVA_HOME set to RI then it will use RI vm and Harmony classes.

Hello Jordan,
Do you mean the build.compiler property in make/build_java.xml? I
just
give it a try by 1) overriding the compiler as what you have done 2)
adding C:\harmony\workspace\trunk\depends\jars\ecj_3.2\ecj_3.2.jar
