使用 antcontrib通过 maven-antrun-plugin 执行任务

我的 maven java 项目使用 maven-antrun-plugin 来执行部署我的应用程序的deploy.xml ant脚本。 deploy.xml 使用 任务,这似乎导致了问题;

[INFO] 执行任务
[taskdef] 无法从资源 net/sf/antcontrib/antlib.xml 加载定义。找不到。

部署:

这是我的 pom 中的 antrun 插件配置;

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

                        <ant antfile="${basedir}/deploy.xml">
                            <target name="deploy" />
                        </ant>
                </tasks>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>

            <version>1.7.1</version>
        </dependency>
    </dependencies>
</plugin>

..这是我的deploy.xml中的相关部分;

<target name="deploy" if="deploy">
    <if>    <!-- line 24 -->
        <and>

为什么我查看我的 Maven 存储库,我可以看到 ant-contrib/ant-contrib/1.0b3/ant-contrib-1.0b3.jar,当我查看 jar 内部时,我可以看到 net /sf/antcontrib/antcontrib.properties 所以没有问题。

当我检查 maven.compile.classpathmaven.compile.classpathmaven.compile.classpath 的值时,我看不到任何参考 antcontrib,这可能是问题所在吗?为什么当 antcontrib 被定义为依赖项时它们不出现?

My maven java project uses the maven-antrun-plugin to execute a deploy.xml ant script that deploys my app. The deploy.xml uses the <if> task and this seems to be causing the problem;

[INFO] Executing tasks
[taskdef] Could not load definitions from resource net/sf/antcontrib/antlib.xml. It could not be found.

deploy:

Cause: The name is undefined.

Here is the antrun plugin config from my pom;

<plugin>

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

                        <ant antfile="${basedir}/deploy.xml">
                            <target name="deploy" />
                        </ant>
                </tasks>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>

            <version>1.7.1</version>
        </dependency>
    </dependencies>
</plugin>

.. and here is the relevant section from my deploy.xml;

<target name="deploy" if="deploy">
    <if>    <!-- line 24 -->
        <and>

Why I look in my maven repo I can see ant-contrib/ant-contrib/1.0b3/ant-contrib-1.0b3.jar and when I look inside the jar I can see net/sf/antcontrib/antcontrib.properties so no problem there.

When I check the values of maven.compile.classpath, maven.compile.classpath and maven.compile.classpath I can't see any reference to antcontrib, could this be the problem? Why don't they appear when antcontrib is defined as a dependancy?

我认为添加 ant 来编译类路径以运行 Maven 插件并不是一个好主意。

我使用 Maven 3.0.4,它通过为 ant-contrib 标签指定命名空间来工作,例如:

<configuration>
  <target>
    <echo message="The first five letters of the alphabet are:"/>
    <ac:for list="a,b,c,d,e" param="letter" xmlns:ac="antlib:net.sf.antcontrib">
      <sequential>
        <echo>Letter @{letter}</echo>
      </sequential>
    </ac:for>
  </target>
</configuration>

我的 maven-antrun-plugin 依赖项:

<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>
  <dependency>
    <groupId>org.apache.ant</groupId>
    <artifactId>ant-nodeps</artifactId>
    <version>1.8.1</version>
  </dependency>
</dependencies>

I think it is not a very good idea to add ant to compile classpath in order to run maven plugin.

I use Maven 3.0.4 and it worked by specifying namespace for ant-contrib tags, for example:

<configuration>
  <target>
    <echo message="The first five letters of the alphabet are:"/>
    <ac:for list="a,b,c,d,e" param="letter" xmlns:ac="antlib:net.sf.antcontrib">
      <sequential>
        <echo>Letter @{letter}</echo>
      </sequential>
    </ac:for>
  </target>
</configuration>

My maven-antrun-plugin dependencies:

<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>
  <dependency>
    <groupId>org.apache.ant</groupId>
    <artifactId>ant-nodeps</artifactId>
    <version>1.8.1</version>
  </dependency>
</dependencies>

我发现您需要在插件中包含 ant-contrib 依赖项,这将使 taskdef 标记能够找到 antcontrib.properties

  <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>

                    </goals>
                    <configuration>
                        <target name = "copy-and-rename-template-files">
                            <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
                            <if>
                                <available file="src/main/resources/docker/templates" type="dir"/>
                                <then>
                                    <copy todir="${project.build.directory}/docker">
                                        <fileset dir="src/main/resources/docker/templates">

                                        </fileset>
                                    </copy>


                                    <move todir="${project.build.directory}/docker">
                                        <fileset dir="${project.build.directory}/docker">
                                            <include name="*"/>
                                        </fileset>
                                        <mapper>
                                            <regexpmapper from="(.*)project(.*)" to="\1${project.artifactId}\2"/>
                                        </mapper>
                                    </move>
                                </then>

                                <else>
                                    <echo>src/main/resources/docker/templates does not exist, skipping processing docker templates</echo>
                                </else>
                            </if>
                        </target>
                    </configuration>
                </execution>
            </executions>
        </plugin>

I found that you need to include the ant-contrib dependency inside the plugin which will enable the taskdef tag to find antcontrib.properties

  <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>

                    <version>20020829</version>
                </dependency>
            </dependencies>
            <executions>
                <execution>
                    <id>copy-and-rename-template-files</id>
                    <phase>prepare-package</phase>

                        <goal>run</goal>
                    </goals>
                    <configuration>
                        <target name = "copy-and-rename-template-files">
                            <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
                            <if>
                                <available file="src/main/resources/docker/templates" type="dir"/>
                                <then>
                                    <copy todir="${project.build.directory}/docker">
                                        <fileset dir="src/main/resources/docker/templates">

                                    </copy>


                                    <move todir="${project.build.directory}/docker">
                                        <fileset dir="${project.build.directory}/docker">

                                        </mapper>
                                    </move>
                                </then>

好的,我已经解决了。

将依赖项移出 标记并将它们与其他项目依赖项一起放入似乎已经成功了。

OK, I've solved it.

Moving the dependencies out of the <build><plugin> tag and putting them in with the other project dependencies seems to have done the trick.

另一个解决方案是:将 ant-contrib-1.0b3.jar 保存到路径中,然后像这样定义它,

<property name="runningLocation" location="" />
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
    <classpath>
        <pathelement location="${runningLocation}/ant-contrib-1.0b3.jar" />
    </classpath>
</taskdef>

然后

<target name="doSomething">
    <if>
        <equals arg1="${someProp}" arg2="YES" />
        <then>
            <echo message="It is YES" />
        </then>
        <else>
            <echo message="It is not YES" />
        </else>
    </if>
</target>

我将完整的代码示例放在这里,您可以下载 https://www.surasint.com/run-ant-with-if-from-maven/

another solution would be: keep the ant-contrib-1.0b3.jar to a path and then define it like this

<property name="runningLocation" location="" />
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
    <classpath>
        <pathelement location="${runningLocation}/ant-contrib-1.0b3.jar" />
    </classpath>
</taskdef>

then

<target name="doSomething">
    <if>
        <equals arg1="${someProp}" arg2="YES" />
        <then>
            <echo message="It is YES" />
        </then>
        <else>
            <echo message="It is not YES" />
        </else>
    </if>
</target>

I put full code example here which you can download https://www.surasint.com/run-ant-with-if-from-maven/
