如何在Ant脚本中调用Maven目标？

Question

是否可以在Ant脚本中调用或执行Maven目标？

假设我有一个名为'distribute'的ant目标,我需要从另一个pom.xml调用maven'compile'目标.

Answer 1

由于没有一个解决方案适合我,这就是我提出的:

假设您在Windows上运行:

<target name="mvn">
    <exec dir="." executable="cmd">
        <arg line="/c mvn clean install" />
    </exec>
</target>

或在UNIX上:

<target name="mvn">
    <exec dir="." executable="sh">
        <arg line="-c 'mvn clean install'" />
    </exec>
</target>

或者如果您希望它在UNIX和Windows上都可以工作:

<condition property="isWindows">
    <os family="windows" />
</condition>

<condition property="isUnix">
    <os family="unix" />
</condition>

<target name="all" depends="mvn_windows, mvn_unix"/>

<target name="mvn_windows" if="isWindows">
    <exec dir="." executable="cmd">
        <arg line="/c mvn clean install" />
    </exec>
</target>

<target name="mvn_unix" if="isUnix">
    <exec dir="." executable="sh">
        <arg line="-c 'mvn clean install'" />
    </exec>
</target>

Answer 2

从Windows CLI使用Maven运行的exec任务的使用示例如下:

<target name="buildProject" description="Builds the individual project">
    <exec dir="${source.dir}\${projectName}" executable="cmd">
        <arg value="/C"/>
        <arg value="${env.MAVEN_HOME}\bin\mvn.bat"/>
        <arg line="clean install" />
</exec>
</target>

Answer 3

您还可以查看现在已经退役的maven ant任务,如下所述.这允许您从ant构建脚本中运行特定的maven目标.你也可以看看这个问题.

Answer 4

你可以使用一个java任务(这个例子类似于@ mateusz.fiolka的答案,但也适用于Linux)

<target name="mvn-install">
    <property environment="env" />
    <path id="classpath">
        <fileset dir="${env.M2_HOME}/boot">
            <include name="plexus-classworlds-*.jar" />
        </fileset>
    </path>
    <property name="mvn.mainclass" value="org.codehaus.plexus.classworlds.launcher.Launcher" />

    <java classname="${mvn.mainclass}" classpathref="classpath" fork="true" failonerror="true">
        <jvmarg value="-Dclassworlds.conf=${env.M2_HOME}/bin/m2.conf" />
        <jvmarg value="-Dmaven.home=${env.M2_HOME}" />
        <arg value="install" />
    </java>
</target>

用maven 3.0.5测试

Answer 5

这里有一个完整的解决方案:

<target name="mvn_windows_setup" if="isWindows">
    <property name="mvn.executable" value="cmd" />
    <property name="mvn.args" value="/c" />
</target>

<target name="mvn_unix_setup" if="isUnix">
    <property name="mvn.executable" value="sh" />
    <property name="mvn.args" value="-c" />
</target>

<target name="run-mvn-goals" depends="mvn_windows_setup, mvn_unix_setup">

    <exec dir="${basedir}" executable="${mvn.executable}">
        <arg line="${mvn.args} 'mvn ${p_goals}'" />
    </exec>

</target>

<!-- EXAMPLES OF HOW TO USE -->

<!-- let's say you want to run mvn clean install -->
<target name="mvn-clean-install">

    <antcall target="run-mvn-goals">
        <param name="p_goals" value="clean install"/>
    </antcall>
</target>

<!-- or maybe you want to clean, package but skipping tests -->
<target name="mvn-clean-package-notests">

    <antcall target="run-mvn-goals">
        <param name="p_goals" value="clean package -DskipTests"/>
    </antcall>
</target>

输出是这样的......
