           Summary: ant task fails if there are java compilation errors
           Product: Kepler
           Version: 1.x dev
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P4
         Component: build system
        AssignedTo: berkley at nceas.ucsb.edu

         QAContact: kepler-dev at kepler-project.org


If "ant tasks" is run and there are compilation errors in the 
build-area/src code, then "ant tasks" will fail to run again
because target/kepler-tasks.jar does not exist.

In the example below, I have some compilation errors and
then ant task fails to run

bash-3.00$  ant task

The workaround is to run

svn update target/; ant task


The fix is to temporarily move targets/kepler-tasks.jar and if
javac fails, then move it back.
