我正在使用 ant maven 插件在 maven 构建中调用遗留目标。当我运行 pom 文件时，它会在丢失的 ant 文件上引发错误：

[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]

我试图添加必要的依赖项，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，org.apache.tools.ant.taskdefs.optional.PropertyFile 类确实存在。我试图将 jar 添加到 $ANT_HOME 内的 lib 目录中，但没有成功。任何光线都会被欣赏。

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 版插件和 1.7 版插件的不同解决方案。

蚂蚁构建.xml

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

maven-antrun-plugin:1.3 pom.xml

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany.app</groupId>
  <artifactId>my-app</artifactId>
  <version>1</version>

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-antrun-plugin</artifactId>
        <configuration>
          <tasks>
            <ant antfile="build.xml" target="run"/>
          </tasks>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>ant</groupId>
            <artifactId>ant-optional</artifactId>

          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>

maven-antrun-plugin:1.7 pom.xml

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany.app</groupId>
  <artifactId>my-app</artifactId>
  <version>1</version>

  <build>
    <plugins>

您的问题与插件相关，因此正常添加正确的 jar<dependency>不会解决问题。

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

依赖项是您项目的一部分，如果没有特殊配置，它们不会部署在您的 ANT 文件夹中。
