21<h1>Ant Tasks</h1>
22
23<p>
24 JaCoCo comes with Ant tasks to launch Java programs with execution recording
Marc R. Hoffmann6fd10ff2010-06-02 21:42:25 +0000[diff] [blame]25 and for creating coverage reports from the recorded data. Execution data can
26 be collected and managed with the tasks
27 <a href="#coverage"><code>coverage</code></a>,
28 <a href="#agent"><code>agent</code></a>,
29 <a href="#dump"><code>dump</code></a> and
30 <a href="#merge"><code>merge</code></a>. Reports in different formats are
31 creates with the <a href="#report"><code>report</code></a> task.
32</p>
33
Marc R. Hoffmannc5d6e802010-07-02 19:34:16 +0000[diff] [blame]34<p class="hint">
35 If you want to have line number information included in the coverage reports
36 or you want source code highlighting the class files of the test target must
37 be compiled with debug information.
38</p>
39
Marc R. Hoffmann6fd10ff2010-06-02 21:42:25 +0000[diff] [blame]40<h2>Example</h2>
41
42<p>
43 The JaCoCo distribution contains a simple example how code coverage can be
44 added to a Ant based build. The
45 <a href="examples/ant/build.xml">build script</a> compiles Java sources, runs
46 the test program and creates a coverage report. The complete example is
47 located in the <code>./doc/examples/ant</code> folder of the distribution.
48</p>
49
50
51<h2>Prerequisites</h2>
52
53<p>
54 The JaCoCo Ant tasks require
Marc R. Hoffmannb8a77462009-08-21 14:53:50 +0000[diff] [blame]55</p>
56
57<ul>
58 <li>Ant 1.7.0 or higher and</li>
59 <li>Java 1.5 or higher (for both, the Ant runner and the test executor).</li>
60</ul>
61
62
Marc R. Hoffmann57f9ab42009-08-24 10:52:42 +0000[diff] [blame]63<p>All tasks are defined in <code>jacocoant.jar</code> (which is part of the
64 distribution) and can be included in your Ant scripts with the usual
65 <code>taskdef</code> declaration:

Marc R. Hoffmanndb3e7d02009-08-12 10:57:39 +0000[diff] [blame]81 Alternatively you might also place the <code>jacocoant.jar</code> in your
82 Ant <code><i>ANT_HOME</i>/lib</code> folder. If you use the name space URI
83 <code>antlib:org.jacoco.ant</code> for JaCoCo tasks Ant will find them
Marc R. Hoffmann6fd10ff2010-06-02 21:42:25 +0000[diff] [blame]84 automatically without the <code>taskdef</code> declaration above. Declaring a
85 XML namespace for JaCoCo tasks is optional but always recommended if you mix
86 tasks from different libraries. All subsequent examples use the
Marc R. Hoffmannf7d17522009-08-07 11:21:23 +0000[diff] [blame]87 <code>jacoco</code> prefix declared above.

Evgeny Mandrikov71b5f6e2011-02-19 22:55:47 +0000[diff] [blame]93 The standard Ant tasks to launch Java programs are <code>java</code>, <code>junit</code> and
94 <code>testng</code>. To add code coverage recording to these tasks they can
Marc R. Hoffmannf7d17522009-08-07 11:21:23 +0000[diff] [blame]95 simply be wrapped with the <code>coverage</code> task as shown in the
96 following examples:

121 to a file when the process terminates. Note the <code>fork</code> attribute
122 above in the wrapped <code>java</code> task.

124
125<p class="hint">
126 The nested task always has to declare <code>fork="true"</code>, otherwise the
127 <code>coverage</code> task can't record coverage information and will fail.
128 In addition the <code>junit</code> task should declare
129 <code>forkmode="once"</code> to avoid starting a new JVM for every single test
130 case and decreasing execution performance dramatically (unless this is
131 required by the nature of the test cases).
132</p>
133
134<p>
135 The coverage task must wrap exactly one task. While it typically works without
136 any configuration, the behavior can be adjusted with some optional attributes:

445<h3>Element <code>executiondata</code></h3>
446
447<p>
448 Within this element Ant resources and resource collections can be specified,
449 that represent JaCoCo execution data files. If more than one execution data
450 file is specified, execution data is combined. A particular piece of code is

459</p>
460

462 <li><code>classfiles</code>: Container element for Ant resources and resource
Marc R. Hoffmannff7cd3a2010-04-06 08:54:29 +0000[diff] [blame]463 collections that can specify Java class files, ZIP archive files (jar, war,
464 ear etc.) or folders containing class files. Archives and folders are
465 searched recursively for class files.</li>
Marc R. Hoffmann2bb6fca2009-08-13 14:04:21 +0000[diff] [blame]466 <li><code>sourcefiles</code>: Optional container element for Ant resources and
Marc R. Hoffmann5625ff62011-03-27 12:53:52 +0000[diff] [blame]467 resource collections that specify corresponding source files. If source
468 files are specified, some report formats include highlighted source code.</li>

Marc R. Hoffmann1f01f862011-01-12 21:58:34 +0000[diff] [blame]498 Note that the <code>classfiles</code> and <code>sourcefiles</code> elements
499 accept any
500 <a href="http://ant.apache.org/manual/Types/resources.html#collection">Ant
501 resource collection</a>. Therefore also filtering the class file set is
502 possible and allows to narrow the scope of the report, for example:

514 <b>Performance Warning:</b> Although it is technically possible and sometimes
515 convenient to use Ant's <code>zipfileset</code> to specify class or source
516 files, this resource type has poor performance characteristics and comes with
517 an huge memory overhead especially for large scale projects.

521 The structure can be refined with a hierarchy of <code>group</code> elements.
522 This way the coverage report can reflect different modules of a software
523 project. For each group element the corresponding class and source files can
524 be specified separately. For example:
