Ant for eclipse - access eclipse configurations from within ant

<hasBuildCommand>

Scope: All Project Types

Description

The hasBuildCommand condition is an Ant Condition that can be used to check if an Eclipse project has a specific buildCommand. An Eclipse project can have several Builders assigned to it. Those builders are normally executed after a file has been saved (incremental build) or when a full build is initiated (Project -> Clean...) (manual build). A typical java project contains the org.eclipse.jdt.core.javabuilder which invokes the default Eclipse compiler on java sources. If you would like to write build steps that depend on specific build commands, you can use the hasBuildCommand condition which checks if a project has a specified buildCommand.

The hasBuildCommand-condition can be used with ant's native condition and waitfor tasks. (See Condition Task). It can also be used with the if-task from the ant-contrib project to create build steps that check whether some specific build commands exist or not.

Arguments

Argument	Description	Required
project	Path to the project for which the output path should be build	either the project or the combination of workspace and projectName has to be specified.
workspace	Path to the workspace containing the projects
projectName	Name of the project inside of the workspace for which the output path should be build
buildCommand	Name of the build command that should be checked	yes

Examples

The following example shows how to use the hasBuildCommand-Condition in conjunction with the if-task from the ant-contrib project


  <target name="build-project">

    <!-- build the project "${project.name}" -->
    <getEclipseClasspath classpathId="myClasspath"
      workspace="${workspace.dir}"
      projectName="${project.name}" />

    <!-- compile only projects with a java builder ... -->
    <if>
      <hasBuildCommand workspace="${workspace.dir}"
                       projectName="${workspace.dir}"
                       buildCommand="org.eclipse.jdt.core.javabuilder"/>
      <then>
        <javac classpathref="myClasspath"
               srcdir="${project.name}/sources"
               destdir="${workspace.dir}/classes"/>
      </then>
    </if>

  </target>
