[kepler-dev] Kepler build problem: Bad Version number

[Christopher Brooks]

My little nightly build failed, and I can reproduce it:

bash-3.2$ ant update
Buildfile: build.xml

BUILD FAILED
/Users/cxh/src/kepler/build-area/build.xml:4: The following error 
occurred while executing this line:
/Users/cxh/src/kepler/build-area/settings/taskdefs.xml:5: 
java.lang.UnsupportedClassVersionError: Bad version number in .class file

Total time: 0 seconds
bash-3.2$

Presumably, the problem is that there is a Java 1.6 .class file
somewhere.

It would be nice if the error message was more explicit and included
a stack trace.

Line 5 of tasksdef.xml is marked below:

<project name="taskdefs">

	<typedef name="get-modules"
         classname="org.kepler.build.Get"
--->    classpath="build-area/target/kepler-tasks.jar"/>

	<typedef name="change-to"
         classname="org.kepler.build.ChangeTo"
		classpath="build-area/target/kepler-tasks.jar"/>


Not much to go on.

This is where having "ant update" build stable versions of
all the components would help.  I realize Kepler is usually much
more stable than Ptolemy, so it is probably not worth it at this
time.

Also, I've not been seeing the NMI build messages lately.  Is it
still running?
