BUILD FAILED java.lang.UnsupportedClassVersionError (Unsupported
major.minor version 49.0)
I had an error while trying to build Lenya trunk today:
ren@ren-ubuntu:~/src/lenya-1.4.x-purevirgin$ ./build.sh
Buildfile: build.xml
BUILD FAILED
java.lang.UnsupportedClassVersionError:
org/apache/lenya/cms/ant/CopyJavaSourcesTask (Unsupported major.minor
version 49.0)
Total time: 2 seconds
This is probably due to the recent changes in:
A tools/anttasks/org/apache/lenya/cms/ant/TwoTuple.java
U tools/anttasks/org/apache/lenya/cms/ant/CopyJavaSourcesTask.class
[...]
To fix it, I deleted the current .class files in
tools/anttasks/org/apache/lenya/cms/ant/ and run
./build.sh compile-build-tasks
HTH,
Renaud

i have the same issue here, java sdk is 1.4.2-11 on linux.
in addition to the fix suggested by renaud, i had to do
rm tools/anttasks/org/apache/lenya/xml/*class
to avoid this error:
bad class file:
/build/lenya/tools/anttasks/org/apache/lenya/xml/AntDocumentHelper.class
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the
classpath.
import org.apache.lenya.xml.AntDocumentHelper;
regards,
jörn

I'm not a commiter ;) but yes building with Java 1.5 works good. I've
recompiled the classes with 1.4, with those lenya builds again with java 1.4
or 1.5. I've attached the 1.4 anttask classes.

or mine ;-) usually, major.minor are caused by Java1.4 - Java1.5 issues.
Are you using 1.5? I am using 1.4.2_10

Maybe a committer using Java 1.4 could try to reproduce the bug,
recompile the classes and check them in?

Strange ... maybe it's due to my Java version?
Thanks for the pointer!
Any hints how to avoid this are very welcome.
