ant - 具有顺序 ant-contrib 的 Maven antrun 无法运行

Question

我们有一个特殊的例程将子文件夹中的文件分解为扩展名，这些扩展名将被复制并打包成单个扩展名文件。对于这种特殊的方法，我想使用maven-antrun-plugin, 对于通过 dirset 的顺序迭代和 jar 打包，我们需要库 ant-contrib。

即将到来的插件配置失败并出现错误。我配置错了什么？谢谢你。

Answer 1

因此我浪费了至少一个小时在下面找到错误提示......

我使用 maven3 和上面描述的其余部分，但我必须使用maven.dependency.classpath 而不是maven.plugin.classpath！否则 maven 将找不到 contrib 任务。希望这对任何人都有帮助。

Answer 2

看起来您缺少声明 ant-contrib tasks所需的taskdef，以便 Ant 知道它们，因此这部分错误消息：

Problem: failed to create task or type for

（如果'for'引用失败的任务 - - 可能会更清楚一些。）

for添加 taskdef 的一种方法是在循环之前立即插入它：

<target>
    <taskdef resource="net/sf/antcontrib/antlib.xml"
             classpathref="maven.plugin.classpath" />
    <for param="extension">
    ...

Answer 3

在浪费了 2 个小时并阅读了太多答案之后，这就是我需要检查的内容

http://www.thinkplexx.com/learn/howto/maven2/plugins/could-not-load-definitions-from-resource-antlib-xml-understanding-the-problem-and-fix-worklow

我使用这个打印了所有的 Maven 类路径

<property name="compile_classpath" refid="maven.compile.classpath"/>
<property name="runtime_classpath" refid="maven.runtime.classpath"/>
<property name="test_classpath" refid="maven.test.classpath"/>
<property name="plugin_classpath" refid="maven.plugin.classpath"/>
<echo message="compile classpath: ${compile_classpath}"/>
<echo message="runtime classpath: ${runtime_classpath}"/>
<echo message="test classpath:    ${test_classpath}"/>
<echo message="plugin classpath:  ${plugin_classpath}"/>

并检查哪个类路径包含 antrib jar 文件。所以我classpathhref改为maven.runtime.classpath从maven.plugin.classpath . 所以我taskdef的是

<taskdef resource="net/sf/antcontrib/antcontrib.properties" classpathref="maven.runtime.classpath" />

和依赖项

<dependency>
  <groupId>ant-contrib</groupId>
  <artifactId>ant-contrib</artifactId>
  <version>1.0b3</version>
  <exclusions>
       <exclusion>
          <groupId>ant</groupId>
          <artifactId>ant</artifactId>
       </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>org.apache.ant</groupId>
  <artifactId>ant-nodeps</artifactId>
  <version>1.8.1</version>
</dependency>

Answer 4

我在这个上也浪费了几个小时，因为找不到 antcontribfor任务。

最后，我发现该for任务不是在中定义的antcontrib.properties，而是在antlib.xml！

antcontrib.properties是蚂蚁 1.6 之前的一种做事方式——现代方式是使用antlib.xml.

所以，这是一个maven 3.5，ant 1.8，工作示例：

<plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <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>

    <execution>
        <id>deploy_to_distrib_folder</id>
        <phase>package</phase>
        <configuration>

            <target>
                <taskdef resource="net/sf/antcontrib/antlib.xml" />

                <macrodef name="deploy_extra_dir">
                    <attribute name="dir" />
                    <sequential>
                        <basename property="basename" file="@{dir}" />
                        <sync todir="${outputDir}/${basename}">
                            <fileset dir="@{dir}" />
                        </sync>
                        <var name="basename" unset="true" />
                    </sequential>
                </macrodef>

                <for param="dir">
                    <path>
                        <dirset dir="${project.build.directory}/maven-shared-archive-resources" includes="*" />
                    </path>
                    <sequential>
                        <deploy_extra_dir dir="@{dir}" />
                    </sequential>
                </for>

            </target>
        </configuration>
        <goals>
            <goal>run</goal>
        </goals>
    </execution>
</plugin>

希望这可以帮助！
