ZipException on javac task moving from jdk1.4 to jdk1.5
Hi there,
I've searched google, ant-faq and ant-manual and found nothing conclusive...
I have recently moved from java (jdk) 1.4.2 to 1.5.0_03.
I'm using ant 1.6.1 (I've tried ant 1.6.5 also, but the problem still
exists)
After deleting all classes and compiling using the javac task (target name
is compile, see code below), I then compile the source again.
The first time I compile (using 'ant compile')it builds successfully.
When I compile again (without modifying any files) and only on jdk1.5.0_03
(it works fine on jdk1.4.2) I get the java.util.zip.ZipException.
Has this happened to anyone? Any ideas on what to do to resolve it?
Thank you for your time,
Fabricio

Posted by Peter Reilly <pe...@apache.org>.
What I wrote below is incorrect.
The problem is due to a difference between javac in jdk1.4 and jdk 1.5.
This can be seen on the command line:
preilly@angel:~/tmp/test > export JAVA_HOME=/usr/java/j2sdk1.4.2
preilly@angel:~/tmp/test > export PATH=$JAVA_HOME/bin:$PATH
preilly@angel:~/tmp/test > javac -classpath hello.java hello.java
preilly@angel:~/tmp/test > export JAVA_HOME=/usr/java/jdk1.5.0
preilly@angel:~/tmp/test > export PATH=$JAVA_HOME/bin:$PATH
preilly@angel:~/tmp/test > javac -classpath hello.java hello.java
error: error reading hello.java; java.util.zip.ZipException: error in
opening zip file
1 error
Sorry for the misleading analysis!

In your case it would be the value
of the reference "compile-classpath".

SOLVED: ZipException on javac task moving from jdk1.4 to jdk1.5
Posted by "Fabricio M. Sanchez" <fa...@pstonline.co.uk>.
Thank you very much, problem is solved!
Maurice, my JAVA_HOME was set to the correct jdk 1.5.0_03 that was being
used by my javac task (I unistalled jdk 1.4.2 to be sure!), thanks for that!
Stefan and Peter, bingo! I did have generated .class files on my
classpath!!!
I followed Peter's advice and removed any references to .class files that
were being generated from my classpath reference
"compile-classpath". This stopped the ZipExceptions appearing, and it builds
successfully again!!!
Although, this doesn't explain why the error did not occurr (with both ant
1.6.1 and 1.6.5) while I was using jdk1.4.2. The error happened only when I
moved to jdk 1.5.0_03....? Maybe it has come back from jdk1.3 as Stefan
suggested...
Thanks again!
Fabricio

This should be a FAQ!
You have a .class file in your class path (i.e. not a directory or a .jar
file). Starting with ant 1.6, ant will open the files in the classpath
checking for manifest entries. This attempted opening will fail with the
error "java.util.zip.ZipException"
The problem does not exist with ant 1.5 as it does not try to open the
files. - so make sure that your classpath's do not contain .class files.

This should be a FAQ!
You have a .class file in your class path (i.e. not a directory
or a .jar file). Starting with ant 1.6, ant will open the
files in the classpath checking for manifest entries. This attempted opening
will fail with the error "java.util.zip.ZipException"
The problem does not exist with ant 1.5 as it does not try to
open the files. - so make sure that your classpath's do not

Re: ZipException on javac task moving from jdk1.4 to jdk1.5
Posted by Maurice Feskanich <Ma...@Sun.COM>.
Don't know if this will help, but I've seen some strange exceptions
moving from jdk 1.4.x to 1.5.x if the JAVA_HOME env var doesn't point to
the same jdk version as the compiler used by the javac task. Make sure
things are in sync. If nothing else, it will rule this out as the cause.

Does your build process modify any jar file that is on your
compile-classpath <path>? Or even worse on CLASSPATH?
I've seen exceptions like this in JDK 1.3 if you modify jars that the
Java VM has opened earlier. Maybe this has come back in 1.5.
