使用unpack-dependencies剥离根目录

Question

我有一个第三方存档（在我的情况下是IntelliJ IDEA CE），它有一个根目录，其名称我无法猜测。在unpack-dependencies任务中，如何在没有根目录的情况下解压缩归档文件？

目前，存档中的所有文件都会被提取到

中

testproject/target/dependency/IntelliJ-IDEA-CE/idea-IC-141.1532.4/

但我希望将它们提取到

中

testproject/target/dependency/IntelliJ-IDEA-CE/

但保留子目录树。

这与在命令行上执行以下操作类似：

cd testproject/target/dependency/IntelliJ-IDEA-CE/
tar -xvf ideaIC-14.1.4.tar.gz --strip 1

我已经在我的本地存储库中安装了存档。这是我的pom.xml文件：
