Java maven antrun：如何迭代文件？

我在以下方面树立了一个榜样：

或者，使用ant排除：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (default) on project antrun-foreach: An Ant BuildException has occured: The following error occurred while executing this line:
[ERROR] /home/travis/build/jjYBdx4IL/example-maven-project-setups/antrun-foreach/pom.xml:5: Unexpected element "{http://maven.apache.org/POM/4.0.0}project" {antlib:org.apache.tools.ant}project
[ERROR] around Ant part ...<foreach param="fileName" target="unzipLibs">... @ 5:48 in /home/travis/build/jjYBdx4IL/example-maven-project-setups/antrun-foreach/target/antrun/build-main.xml

将ant任务移动到外部文件中没有帮助

更新：问题似乎是maven antrun插件不支持定义多个antrun目标

通过将目标定义移动到单独的ant xml构建文件中来解决
