How to use jococo ant task with already compiled/build java code ?
kta...@gmail.com
I am new to java and this plugin :)
I am having the complete build/compiled java code with me for swtbot tests. Now i want to see what all code/features has been covered from these tests. So tried to use the ant tasks of jacoco mentioned at
http://www.eclemma.org/jacoco/trunk/doc/ant.html
and referenced
http://www.eclemma.org/jacoco/trunk/doc/examples/build/build.xml too.
when i am giving the report target as
<target name="report" depends="suite">
<!-- Step 3: Create coverage report -->
<jacoco:report>
<!-- This task needs the collected execution data and ... -->
<executiondata>
<file file="${result.exec.file}" />
</executiondata>
<!-- the class files and optional source files ... -->
<structure name="JaCoCo report">
<classfiles>
<fileset dir="${result.classes.dir}" />
</classfiles>
</structure>
<!-- to produce reports in different formats. -->
<html destdir="${result.report.dir}" />
<csv destfile="${result.report.dir}/report.csv" />
<xml destfile="${result.report.dir}/report.xml" />
</jacoco:report>
</target>
and coverage as
<jacoco:coverage destfile="${result.exec.file}">
<java fork="true" dir="." timeout="${timeout}" jvm="${jvm}" logError="true" classname="org.eclipse.core.launcher.Main" output="${junit-report-output}/${classname}.txt">
<classpath>
<fileset dir="${eclipse-home}/plugins">
<include name="org.eclipse.equinox.launcher_*.jar" />
</fileset>
</classpath>
<arg line="${launcher-arg-line}" />
<jvmarg line="${jvm-arg-line}" />
<sysproperty key="PLUGIN_PATH" value="${plugin-path}" />
</java>
</jacoco:coverage>
where ${result.classes.dir} (i.e. ${eclipse-home}/plugins) points to my already compiled code directory containing many .class and .jar under different folders.
.exec and index.html and .session.html files are getting generated but result is not correct and command prompt it shows
BUILD FAILED : Error while creating report.
. It is not listing all the classes and .sessions.html lists many classes but with no links to direct to that class and see the executed methods .
And when i run the EclEmma eclipse plugin from eclipse and run and see the result there then that it is working absolutely fine.
So i am just wandering what is missing in case of ant tasks ?

Why does the coverage report not show highlighted source code?
Make sure the following prerequisites are fulfilled to get source code highlighting in JaCoCo coverage reports:
- Class files must be compiled with debug information to contain line numbers.
- Source files must be properly supplied at report generation time. I.e. specified source folders must be the direct parent of the folders that define the Java packages.

the JaCoCo Ant task does not support providing ZIP (Jar) files for the source code. Also your include
<include name="com.xyz.xide*.jar/src"/>
will probably not match with any file.
The only chance to fix this is to either unzip the JARs first or try to use zipfilesets instead of the dirset:
<zipfileset src="com.xyz.xide.jar" prefix="src"/>
But I haven't tried the latter myself.
Cheers,
