Question

我正在使用maven-antrun-plugin在maven项目中调用ant build。 ant构建声明了一个taskdef，我需要将taskdef的类路径设置为由与maven-antrun-plugin（即maven.plugin.classpath）相关联的依赖项以及一些其他资源组成。我只能将类路径变为maven.plugin.classpath。

我的pom.xml的片段

            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
            <version>1.8</version>
            <executions>
                <execution>
                    <phase>test</phase>
                    <configuration>
                        <target>

                            <path id="my.classpath">
                                <pathelement location="src/test/resources" />
                                <path refid="maven.plugin.classpath" />
                            </path>

                            <property name="my_classpath" refid="my.classpath" />
                            <property name="plugin_classpath" refid="maven.plugin.classpath"/>

                            <echo message="my classpath:  ${my_classpath}"/>
                            <echo message="plugin classpath:  ${plugin_classpath}"/> 

                            <!-- define the taskdef, specifying the classpathref from above -->
                            <taskdef name="sqlunit" classname="net.sourceforge.sqlunit.ant.SqlunitTask" classpathref="my.classpath"/>

                             <!-- invoke the tests -->
                            <sqlunit>
                              <fileset dir="src/test/db">
                                <include name="**/*.xml" />
                              </fileset>
                            </sqlunit>                                
                        </target>
                    </configuration>
                    <goals>
                        <goal>run</goal>
                    </goals>
                </execution>
            </executions>

在SQLUnit中，我打印出类路径的URL：

    ClassLoader cl = SQLUnit.class.getClassLoader();

    URL[] urls = ((URLClassLoader)cl).getURLs();

    for(URL url: urls){
        System.out.println(url.getFile());
    }

执行“mvn test”，我可以看到my.classpath包含src / test / resources：

当执行sqlunit任务时，我发现类路径只包含maven.plugin.classpath中找到的那些工件。

/Users/szalwinb/.m2/repository/org/apache/maven/plugins/maven-antrun-plugin/1.8/maven-antrun-plugin-1.8.jar

我查看了AntRunMojo的源代码，我看到的是构建一个Ant项目并添加maven.plugin.classpath作为项目的引用。

        /* set maven.plugin.classpath with plugin dependencies */
        antProject.addReference( "maven.plugin.classpath", getPathFromArtifacts( pluginArtifacts, antProject ) );

我认为正在发生的事情是taskdef能够使用添加到项目中的引用来解析其类，因此它忽略了与taskdef元素关联的classpathref。为了证明这个理论，我从taskdef中删除了classpathref属性，

 <taskdef name="sqlunit" classname="net.sourceforge.sqlunit.ant.SqlunitTask"/>

任务仍然可以解决它的课程。当类加载器打印出它的资源时，它们就是由maven.plugin.classpath定义的。

===============

我最终更改了SQLUnit的构建，以便log4j.properties文件包含在sqlunit.jar中。现在一切都很开心。
