在maven ant插件中使用ant脚本

Question

我正在使用ant maven插件来调用maven构建中的遗留目标。当我运行pom文件时，它抛出一个关于缺少ant文件的错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.3:run (clear-generated-javascripts) on project documentation: An Ant BuildException has occured: The following error occurred while executing this line:
[ERROR] C:\Development\documentation\build.xml:308: Problem: failed to create task or type propertyfile
[ERROR] Cause: the class org.apache.tools.ant.taskdefs.optional.PropertyFile was not found.
[ERROR] This looks like one of Ant's optional components.
[ERROR] Action: Check that the appropriate optional JAR exists in
[ERROR] -ANT_HOME\lib
[ERROR] -the IDE Ant configuration dialogs
[ERROR]
[ERROR] Do not panic, this is a common problem.
[ERROR] The commonest cause is a missing JAR.
[ERROR]

我尝试添加必要的依赖项，如下所示：

<dependency>
    <groupId>ant</groupId>
    <artifactId>ant-optional</artifactId>
    <version>1.5.2</version>
</dependency>

我查看了ant-optional jar文件，发现org.apache.tools.ant.taskdefs.optional.PropertyFile类确实存在。我尝试将jar添加到$ANT_HOME内的lib目录中，但没有成功。任何光线都会被消除。

Answer 1

您的问题是与插件相关的，因此将正确的<dependency>添加为普通jar不会解决问题。

您需要将包含org.apache.tools.ant.taskdefs.optional.PropertyFile的JAR添加到%ANT_HOME%\lib

依赖项应该是你项目的一部分，如果没有特殊的配置，它们不会被部署到你的ANT文件夹中。

Answer 2

您发布的错误消息显示您正在使用maven-antrun-plugin:1.3。我发现使用1.3版本的插件和1.7版本的插件有不同的解决方案。

蚂蚁build.xml

<project name="ant-propertyfile" basedir=".">
    <target name="run">
        <propertyfile file="my.properties" comment="My properties">
            <entry key="progress" value="Made"/>
        </propertyfile>
    </target>
</project>
