| Calls a given target for all defined sub-builds. |
| This is an extension |
| of ant for bulk project execution. |
| |
| <strong>This task must no be used outside of a |
| <code>target</code> if it invokes the same build file it is |
| part of.</strong> |
| </p> |
| <subsection name="Use with directories"> |
| <p> |
| subant can be used with directory sets to execute a build from different directories. |
| 2 different options are offered : |
| </p> |
| <ul> |
| <li> |
| to run the same build file <code>/somepath/otherpath/mybuild.xml</code> |
| with different base directories, use the genericantfile attribute |
| </li> |
| <li>if you want to run <code>directory1/mybuild.xml</code>, <code>directory2/mybuild.xml</code>, <code>....</code>, |
| use the antfile attribute. The subant task does not set the base directory for you in this case, because you can specify it in each build file. |
| </li> |
| </ul> |

| <p> |
| this snippet build file will run ant in each subdirectory of the project directory, |
| where a file called build.xml can be found. |
| The property build.dir will have the value subant1.build in the ant projects called by subant. |
| </p> |
| <pre> |
| <subant target=""> |

| <p> |
| this snippet build file will run ant in each subdirectory of the project directory, |
| where a file called build.xml can be found. |
| All properties whose name starts with "foo" are passed, their names are changed to start with "bar" instead |
| </p> |
| <pre> |
| <subant target="compile" genericantfile="/opt/project/build1.xml"> |
| <dirset dir="." includes="projects*"/> |
| </subant> |
| </pre> |
| <p> |
| assuming the subdirs of the project dir are called projects1, projects2, projects3 |
| this snippet will execute the compile target of /opt/project/build1.xml, |
| setting the basedir to projects1, projects2, projects3 |
