Installation of jacoco ant tasks on CentOS

[Martin Schmude]

Hello,

on a CentOS 7 system I want to use jacoco in an ant script.

In the <taskdef> element I want to avoid the nested <classpath> element.

It should not look like

1. <taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml">
   
2. <classpath path="/some/path/jacocoant.jar"/>
   
3. </taskdef>

 

but simply

1. <taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml" />

Following the ant documentation this could be achieved by storing the jacocoant.jar in the lib subfolder of $ANT_HOME. On my system this results in/usr/share/ant/lib.

I did the same successfully with other ant addons, e.g. ant-junit. But with jacoco it doesn't work.

The output of the ant script when evaluating the taskdef is:

Buildfile: /tmp/build.xml
 [taskdef] Could not load definitions from resource org/jacoco/ant/antlib.xml. It could not be found.

When executing ant -diagnostics I find this section in the output:

------------------------------------------- ANT_HOME/lib jar listing -------------------------------------------
ant.home: /usr/share/ant ant-bootstrap.jar (20919 bytes)
ant-launcher.jar (19065 bytes)
ant.jar (1999722 bytes)
ant-commons-net.jar (91879 bytes) 
ant-antlr.jar (12272 bytes) 
ant-jsch.jar (47207 bytes) 
ant-contrib-1.0b3.jar (196539 bytes) 
ant-junit.jar (113254 bytes) 
ant-junit4.jar (13782 bytes) 
junit.jar (290000 bytes) 
hamcrest-all.jar (122201 bytes) 
jacocoant.jar (31856 bytes)

So ant finds the jacocoant.jar.

Any help welcome! Thanks in advance.

I forgot to mention:

The ant version

Apache Ant(TM) version 1.9.2 compiled on June 10 2014

The Java version

openjdk version "1.8.0_141"

OpenJDK Runtime Environment (build 1.8.0_141-b16)

OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)

The jacoco version is  0.8.1.

Also note: when I put the classpath element into the taskdef, the problem is gone.

So as a workaround I could use the builtin ant.home property like this:

<taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml">

    <classpath path="${ant.home}/lib/jacocoant.jar"/>

</taskdef>

Hi Martin,

Your "jacocoant.jar" is too small.

"jacocoant.jar" of version 0.8.1 has following size and checksums:

$ ls -g jacoco-0.8.1/lib/jacocoant.jar

-rw-r--r-- 1 wheel 663345 Mar 21 10:39 jacoco-0.8.1/lib/jacocoant.jar

$ sha256sum jacoco-0.8.1/lib/jacocoant.jar

eb375296cb836c202f35b711fee2a41bbeb447b80e54dd1fd05ef6c1d75774e3  jacoco-0.8.1/lib/jacocoant.jar

$ md5sum jacoco-0.8.1/lib/jacocoant.jar

Hello Evgeny,

you are right. I accidentally posted the wrong output of ant -diagnostics - I'm sorry. Here is the correct one:

ant.home: /usr/share/ant
ant-bootstrap.jar (20919 bytes)
ant-launcher.jar (19065 bytes)
ant.jar (1999722 bytes)
ant-commons-net.jar (91879 bytes)
ant-antlr.jar (12272 bytes)
ant-jsch.jar (47207 bytes)
ant-contrib-1.0b3.jar (196539 bytes)
ant-junit.jar (113254 bytes)
ant-junit4.jar (13782 bytes)

sonar-ant-task-2.1.jar (1842861 bytes)
sonar-ant-task-2.2.jar (1825821 bytes)

junit.jar (290000 bytes)
hamcrest-all.jar (122201 bytes)

catalina-ant.jar (54802 bytes)
tomcat-coyote.jar (775617 bytes)
tomcat-juli.jar (38160 bytes)
tomcat-util.jar (23078 bytes)
jacocoant.jar (663345 bytes)

Which conforms to the file size of the jacocoant.jar, that you posted.

[Martin Schmude]

I just looked at the checksums, and they are also the ones that you posted.

Nevertheless the problem remains.
