[kepler-dev] ant update fails with UnsupportedClassVersion error

[Christopher Brooks]

Hi Aaron,

It looks like your recent change to kepler-tasks.jar breaks the build
for Java 1.5 users.  Perhaps you compiled with Java 1.6?

The change was:
------------------------------------------------------------------------
r20802 | aschultz | 2009-09-27 22:24:41 -0700 (Sun, 27 Sep 2009) | 1 line



Here's the error:

bash-3.2$ pwd
/Users/cxh/src/kepler/build-area
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

If I check out the previous version, then all is well:


bash-3.2$ svn update -r 20782 target/kepler-tasks.jar
U    target/kepler-tasks.jar
Updated to revision 20782.
