[fedora-java] Ant launcher script
Hi,
We've had IcedTea8 failing for some time on our Fedora build machine:
JAVA_HOME=/notnfs/nighttester/icedtea8-target-testing/bootstrap/jdk1.6.0
ANT_OPTS=-Djava.io.tmpdir='/notnfs/nighttester/icedtea8-target-testing/openjdk.build/langtools/build/ant-tmp'
/usr/bin/ant -diagnostics >
/notnfs/nighttester/icedtea8-target-testing/openjdk.build/langtools/build/ant-diagnostics.log
; \
JAVA_HOME=/notnfs/nighttester/icedtea8-target-testing/bootstrap/jdk1.6.0
ANT_OPTS=-Djava.io.tmpdir='/notnfs/nighttester/icedtea8-target-testing/openjdk.build/langtools/build/ant-tmp'
/usr/bin/ant -version >>
/notnfs/nighttester/icedtea8-target-testing/openjdk.build/langtools/build/ant-diagnostics.log
Error: Could not find or load main class org.apache.tools.ant.launch.Launcher
Error: Could not find or load main class org.apache.tools.ant.launch.Launcher
make[3]: ***
[/notnfs/nighttester/icedtea8-target-testing/openjdk.build/langtools/build/ant-diagnostics.log]
Error 1
while it succeeds fine for me locally. I've finally managed to have a quick look at
why this is, motivated by the fact that the 6 builds also broke when we upgraded to F16
(though for a different reason).
It seems the Ant script calls /usr/bin/build-classpath by default which in turn runs
/usr/share/java-utils/java-functions. It is set_jvm_dirs in this which fails as it
can't find /usr/share/java-1.8.0:
$ JAVA_HOME=/notnfs/nighttester/icedtea8-target-testing/bootstrap/jdk1.6.0
ANT_OPTS=-Djava.io.tmpdir='/notnfs/nighttester/icedtea8-target-testing/openjdk.build/langtools/build/ant-tmp'
/usr/bin/ant --execdebug -diagnostics
exec "/notnfs/nighttester/icedtea8-target-testing/bootstrap/jdk1.6.0/bin/java"
-Djava.io.tmpdir=/notnfs/nighttester/icedtea8-target-testing/openjdk.build/langtools/build/ant-tmp
-classpath "/usr/bin/build-classpath: error: JAVAVER_LIBDIR /usr/share/java-1.8.0
does not exist or is not a
directory:/notnfs/nighttester/icedtea8-target-testing/bootstrap/jdk1.6.0/lib/tools.jar"
-Dant.home="/usr/share/ant" -Dant.library.dir="/usr/share/ant/lib"
org.apache.tools.ant.launch.Launcher -cp "" "-diagnostics"
Error: Could not find or load main class org.apache.tools.ant.launch.Launcher
Obviously this doesn't yet exist as there is no system 1.8 install. I don't see
why this is worth causing an error and dropping out of the script. Indeed, if
the following lines are commented out:
# elif [ ! -d "$JAVAVER_LIBDIR" ]; then
# echo "$0: error: JAVAVER_LIBDIR $JAVAVER_LIBDIR does not exist or is not a
directory"
# return 1
# elif [ ! -d "$JAVAVER_JNIDIR" ]; then
# echo "$0: error: JAVAVER_JNIDIR $JAVAVER_JNIDIR does not exist or is not a
directory"
# return 1
the script works fine and produces the same classpath as for 1.6 or 1.7:
JAVA_HOME=/notnfs/nighttester/icedtea8-target-testing/bootstrap/jdk1.6.0 build-classpath
ant ant-launcher jaxp_parser_impl xml-commons-apis
/usr/share/java/ant.jar:/usr/share/java/ant-launcher.jar:/usr/share/java/jaxp_parser_impl.jar:/usr/share/java/xml-commons-apis.jar
So /usr/share/java-${ver} isn't used anyway. java-1.5.0, java-1.6.0 and java-1.7.0
all exist
but are empty.
Given the script will allow the user to set JAVA_HOME, and this can be to a version <
1.5 or > 1.7,
I see no reason why it shouldn't just silently ignore the path if it doesn't
exist, rather than
erroring out.
It's possible to workaround this by passing --noconfig to /usr/bin/ant and setting
ANT_HOME, but
I don't know what effect this will have on the numerous other ant scripts on other
distributions,
not to mention how we work out what to set ANT_HOME to in the first place. Fixing this
script
on the problem distro (Fedora) seems like a much simpler solution.
Would this be possible?
