我想在我的项目中使用一些 liferay 工件（2 更改 Jboss Portal 4 liferay，但这是另一个故事）。我从 forge.net/projects/lportal/files/Liferay%20Portal/6.1.0%20GA1/liferay-portal-maven-6.1.0-ce-ga1-20120106155615760.zip/download 下载 maven liferay 插件键入 ant install auto 自动将 liferay 工件安装到 maven 存储库中（没有更改 build.xml 中的任何内容，方向也，因为我想将它安装到默认存储库 USER/.m2 中。所以我在 cmd 中键入 ant instal -debug 并且我得到这个错误
