由 Maven 构建

使用 Ant 的默认 jar 中未包含的任务

要使用 Ant jar 中未包含的 Ant 任务，例如 Ant 可选任务或自定义任务，您需要将任务运行所需的依赖项添加到插件类路径中，并在需要时使用maven.plugin.classpath引用。

<project>
  <modelVersion>4.0.0</modelVersion>
  <artifactId>my-test-app</artifactId>
  <groupId>my-test-group</groupId>
  <version>1.0-SNAPSHOT</version>

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>3.0.0</version>
        <executions>
          <execution>
            <id>ftp</id>
            <phase>deploy</phase>
            <configuration>
              <target>

                <ftp action="send" server="myhost" remotedir="/home/test" userid="x" password="y" depends="yes" verbose="yes">
                  <fileset dir="${project.build.directory}">
                    <include name="*.jar" />
                  </fileset>
                </ftp>

                <taskdef name="myTask" classname="com.acme.MyTask" classpathref="maven.plugin.classpath"/>
                <myTask a="b"/>

              </target>
            </configuration>
            <goals>
              <goal>run</goal>
            </goals>
          </execution>
        </executions>
        <dependencies>
          <dependency>
            <groupId>commons-net</groupId>
            <artifactId>commons-net</artifactId>
            <version>1.4.1</version>
          </dependency>
          <dependency>
            <groupId>org.apache.ant</groupId>
            <artifactId>ant-commons-net</artifactId>
            <version>1.8.1</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>

另一个例子是使用Ant-Contrib任务：

<project>
  [...]
  <build>
    [...]
    <plugins>
      [...]
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>3.0.0</version>
        <executions>
          <execution>
            [...]
            <configuration>
              <target>
                <taskdef resource="net/sf/antcontrib/antcontrib.properties" classpathref="maven.plugin.classpath"/>
                [...]
              </target>
            </configuration>
            <goals>
              <goal>run</goal>
            </goals>
          </execution>
        </executions>
        <dependencies>
          <dependency>
            <groupId>ant-contrib</groupId>
            <artifactId>ant-contrib</artifactId>
            <version>1.0b3</version>
            <exclusions>
              <exclusion>
                <groupId>ant</groupId>
                <artifactId>ant</artifactId>
              </exclusion>
            </exclusions>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>
