Description Philippe Van Deyck 2004-11-28 20:25:01 UTC

Emerging ant-tasks (1.6.2-r5), using jikes as java-compiler, produces error while compiling ant classes.
The error says my classpath is incorrect, but that's not the case. The ebuild changes it incorrectly. Jikes (1.22) needs the $JAVA_HOME/jre/lib/rt.jar in its classpath, but the ant-tasks ebuild changes it to "." (on line 68).

Reproducible: Always
Steps to Reproduce:
1.emerge ant-tasks
2.
3.

Actual Results:  
Calculating dependencies ...done!

Found 1 system error:

*** Semantic Error: You need to modify your classpath, sourcepath, 
bootclasspath, and/or extdirs setup. Jikes could not find package "java.lang" 
in:
                build/classes
                src/main
                lib/xercesImpl.jar
                lib/xml-apis.jar
                .
                /opt/blackdown-jdk-1.4.2/lib/tools.jar
                .

... Failed compiling Ant classes !

Expected Results:  
No error.

When i change the classpath in the ebuild on line 68, from:
CLASSPATH="." ./build.sh -Ddist.dir=${D}/usr/share/ant-core -lib ${libs} || die 
"build failed"

to:
CLASSPATH=".:$JAVA_HOME/jre/lib/rt.jar" ./build.sh -Ddist.dir=${D}/usr/share/
ant-core -lib ${libs} || die "build failed"

The ebuild finishes succesfully. Don't know if it's the correct solution, but it 
works.

Please include the output of 'emerge info' as an attachment as well as the jdk being used.  Please reopen when the required information has been attached.

I tested for this and found nothing wrong. I used blackdown-jdk-1.4.2.01. 

Here's how I did it:
qpkg -I -nc dev-java | xargs emerge -C 
USE="jikes" emerge ant-tasks
