In particular you need a 27 <a href="http://maven.apache.org/">Maven 3</a> installation. Developers are 28 encouraged to run the build before every commit to ensure consistency of the 29 source tree. 30</p> 31 32 33<h2>Running the Build</h2> 34 35<p> 36 The build can be started by executing the following command with 37 <code>./org.jacoco.build/</code> as the working directory: 38</p> 39 40<pre> 41 mvn clean install 42</pre> 43 44<p> 45 Total build time is typically around 3 minutes, however first build might take 46 more time, because Maven should download plugins and dependencies. The 47 download ZIP will be created at the following location: 48</p> 49 50<pre> 51 ./jacoco/target/jacoco-<i>x.y.z.qualifier</i>.zip 52</pre> 53 54 55<h2>Running Quick Build without Tests</h2> 56 57<p> 58 It is not recommended, however possible to the run build without any tests: 59</p> 60 61<pre> 62 mvn clean install -DskipTests 63</pre> 64 65 66<h2>Testing with different JDKs</h2> 67 68<p> 69 Target Java version for JaCoCo builds is 1.5, however for verification 70 purposes you can execute tests using other versions. In order to do so, first 71 you should create file <code>toolchains.xml</code> in <code>~/.m2/</code> 72 directory. Here is an example of such file.

Note that in this case 165 the version of the JVM running Maven must be at least the version of the 166 specified bytecode version as this JVM is also running the tests. Combining 167 these options JaCoCo is regularly tested with the following setups: 168</p> 169 170<ul> 171 <li>Maven with 1.5 JDK: <code>mvn clean install -Djdk.version=1.5 -Dbytecode.version=1.5</code></li> 172 <li>Maven with 1.6 JDK: <code>mvn clean install -Djdk.version=1.6 -Dbytecode.version=1.6</code></li> 173 <li>Maven with 1.7 JDK: <code>mvn clean install -Djdk.version=1.7 -Dbytecode.version=1.7</code></li> 174 <li>Maven with 1.8 JDK: <code>mvn clean install -Djdk.version=1.8 -Dbytecode.version=1.8</code></li> 175 <li>Maven with 1.8 JDK: <code>mvn clean install -Djdk.version=1.8 -Dbytecode.version=1.8 -Decj</code></li> 176 <li>Maven with 1.9 JDK: <code>mvn clean install -Djdk.version=1.9 -Dbytecode.version=1.9</code></li> 177</ul> 178 179 180</div> 181<div class="footer"> 182 <span class="right"><a href="@jacoco.home.url@">JaCoCo</a> @qualified.bundle.version@</span> 183 <a href="license.html">Copyright</a> © @copyright.years@ Mountainminds GmbH & Co.
