Subject Re: org.apache.hadoop.hbase.coprocessor.TestClassLoading failing in Eclipse, not in shell...
Date Wed, 30 Jan 2013 14:03:48 GMT
Hi Ted,

You have a point for the JVM!

MVN is running with: Java home: /usr/lib/jvm/java-6-openjdk-amd64/jre
And Eclikpse with /usr/local/jdk1.7.0_05/

I change alligned the 2 to point to 1.7 but I'm still getting the same results.


>From mvn:
Running org.apache.hadoop.hbase.coprocessor.TestClassLoading
Tests run: 7, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 40.215 sec



>From the eclipse console, for TestClassLoading.testHBase3810 I can see this:

Exact same 2 issues.

Here is the related code:
    String classpath =
        currentDir + File.separator + "target"+ File.separator + "classes" +
        System.getProperty("path.separator") +
        // Note that the below trick only works if mvn is running the test;
        // doesn't work in eclipse for example.
        System.getProperty("surefire.test.class.path");

That's why it's not working in Eclipse ;)

We should read the classpath from eclipse and add it too to this string...
