Error: "Copying source file <Unknown>"
I am working on a Jenkins project on a shared server managed by my school. My build.xml file has the following steps to execute FindBugs:
<target name="findbugs"> <echo>FindBugs Starting:</echo> <available file="${findbugs.dir}/findbugs.jar" property="findbugs.available" /> <fail unless="findbugs.available" message="Error: FINDBUGS_HOME not set or findbugs.jar not found." /> <taskdef name="findbugs" classname="edu.umd.cs.findbugs.anttask.FindBugsTask" classpath="${findbugs.dir}/findbugs-ant.jar" /> <findbugs home="${findbugs.dir}" workHard="true" output="xml:withMessages" outputFile="${report.dir}/findbugs.xml" excludefilter="findbugs-exclusions.xml" sourcePath="${src.dir}" > <class location="${classes.dir}" /> <auxClasspath> <fileset file="${lib.dir}/junit.jar" /> </auxClasspath> </findbugs> <echo>FindBugs finished</echo> </target> When executed, the output to the Jenkins console does not contain errors, but shows a clean execution, as far as I can tell:
[echo] FindBugs Starting: [findbugs] Executing findbugs from ant task [findbugs] Running FindBugs... [findbugs] Warnings generated: 24 [findbugs] Calculating exit code...

If an additional structure is needed, the full source and binaries of the file can be found at https://github.com/jenrmagas/RedditDailyProgrammer , and it should work from build to Ant.
