     21 <h1>Build</h1>
     22 
     23 <p>
     24   The JaCoCo build is fully based on <a href="http://maven.apache.org/">Maven</a>
     25   and its extension <a href="http://www.eclipse.org/tycho/">Tycho</a> to build
     26   OSGi bundles based on the declations in their <code>MANIFEST.MF</code> file
     27   ("manfest-first" approach). The build can be locally executed on every machine
     28   with a proper <a href="environment.html">environment setup</a>. In particular
     29   you need a <a href="http://maven.apache.org/">Maven 3</a> installation. 
     30   Developers are encouraged to run the build before every commit to ensure
     31   consistency of the source tree.
     32 </p>
     33 
     34 
     35 <h2>Running the Build</h2>
     36 
     37 <p>
     38   The build can be started by executing the following command with
     39   <code>./org.jacoco.build/</code> as the working directory:
     40 </p>
     41 
     42 <pre>
     43   mvn clean install
     44 </pre>
     45 
     46 <p>
     47   Total build time is typically around 3 minutes, however first build might take
     48   more time, because Maven should download plugins and dependencies. The
     49   download ZIP will be created at the following location:
     50 </p>
     51 
     52 <pre>
     53   ./org.jacoco.doc/target/jacoco-<i>x.y.z.qualifier</i>.zip
     54 </pre>
     55 
     56 
     57 <h2>Running Quick Build without Tests</h2>
     58 
     59 <p>
     60   It is not recommended, however possible to the run build without any tests:
     61 </p>
     62 
     63 <pre>
     64   mvn clean install -DskipTests
     65 </pre>
     66 
     67 
     68 <h2>Testing with different JDKs</h2>
     69 
     70 <p>
     71   Target Java version for JaCoCo builds is 1.5, however for verification
     72   purposes you can execute tests using other versions. In order to do so, first
     73   you should create file <code>toolchains.xml</code> in <code>~/.m2/</code>
     74   directory. Here is an example of such file. For more information see
     75   <a href="http://maven.apache.org/guides/mini/guide-using-toolchains.html">Maven
     76   Guide to Using Toolchains</a>.

    108       &lt;version&gt;1.7&lt;/version&gt;
    109       &lt;vendor&gt;sun&lt;/vendor&gt;
    110     &lt;/provides&gt;
    111     &lt;configuration&gt;
    112       &lt;jdkHome&gt;/usr/lib/jvm/sun-jdk-1.7&lt;/jdkHome&gt;

    119       &lt;version&gt;1.8&lt;/version&gt;
    120       &lt;vendor&gt;sun&lt;/vendor&gt;
    121     &lt;/provides&gt;
    122     &lt;configuration&gt;
    123       &lt;jdkHome&gt;/usr/lib/jvm/sun-jdk-1.8&lt;/jdkHome&gt;
    124     &lt;/configuration&gt;
    125   &lt;/toolchain&gt;
    126 &lt;/toolchains&gt;
    127 </pre>
    128 
    129 <p>
    130   Now you should be able to execute maven build with specified version of JDK:
    131 </p>
    132 
    133 <pre>
    134   mvn clean install -Djdk.version=<i>version</i>
    135 </pre>
    136 
    137 <p>
    138   Location of <code>toolchains.xml</code> can be set via an option:
    139 </p>
    140 
    141 <pre>
    142   mvn --toolchains <i>path</i> clean install -Djdk.version=<i>version</i>
    143 </pre>
    144 
    145 <p>
    146   In addition JaCoCo can be compiled for higher class file versions than 1.5
    147   specifying the property <code>bytecode.version</code>. Note that in this case
    148   the version of the JVM running Maven must be at least the version of the
    149   specified bytecode version as this JVM is also running the tests. Combining
    150   these options JaCoCo is regularly tested with the following setups:
    151 </p>
    152 
    153 <ul>
    154   <li>Maven with 1.5 JDK: <code>mvn clean install -Djdk.version=1.5 -Dbytecode.version=1.5</code></li>
    155   <li>Maven with 1.6 JDK: <code>mvn clean install -Djdk.version=1.6 -Dbytecode.version=1.6</code></li>
    156   <li>Maven with 1.7 JDK: <code>mvn clean install -Djdk.version=1.7 -Dbytecode.version=1.7</code></li>
    157   <li>Maven with 1.8 JDK: <code>mvn clean install -Djdk.version=1.8 -Dbytecode.version=1.8</code></li>
    158 </ul>
