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.

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> 159 160 161</div> 162<div class="footer"> 163 <span class="right"><a href="@jacoco.home.url@">JaCoCo</a> @qualified.bundle.version@</span> 164 <a href="license.html">Copyright</a> © @copyright.years@ Mountainminds GmbH & Co.
