| Weird error with Jar task | Weird error with Jar task 2005-06-21 - By Frank W. Zammetti
Actually, based on some further Googling, I think I stumbled on the
answer (and I do mean stumbled!)...
It appears that the cause of the problem is my Checkstyle task...
<target name="checkstyle">
<echo message="Performing static code analysis using CheckStyle..." />
<delete file="${src}/checkstyle_results.xml" />
<taskdef resource="checkstyletask.properties">
<classpath location="${src}/lib/checkstyle-all.jar" />
</taskdef>
<checkstyle config="${otherlibs}/checkstyle_checks.xml"
failOnViolation="false">
<classpath refid="classpath" />
<fileset dir="${src}/org" includes="**/*.java" />
<formatter type="xml" toFile="${src}/checkstyle_results.xml" />
</checkstyle>
<echo message="Done" />
</target>
It seems like it might be a file locking issue... I found a Bugzilla
ticket that was much like my problem, but the cause was some unnamed
other task. Not sure it was Checkstyle in that case, but seems to be here.
Not a big problem, I can just move the Checkstyle task to after the JAR
update task, but does anyone know for sure what is going on?
