Java 无法执行目标org.apache.maven.plugins（权限被拒绝）

我在ubuntu 14.04上构建maven项目时遇到了这个错误。我的命令：mvn-liferay:build-service编译包

之后，我使用sudo:$sudomvnliferay:buildservice编译包运行

---

权限，但仍然无法解决此问题，请帮助我。

文件可能已被其他进程锁定：

执行lsof/usr/lib/jvm/java-7-openjdk-i386/jre/lib/ext/mysql-connector-java-5.1.21.jar

---

查看哪个进程可能持有独占锁。

看起来您正在通过绝对路径使用依赖项，这绝不是一个好主意。最好开始使用存储库管理器，并将此类工件部署到单独的存储库中。这会解决很多头疼的问题。谢谢你，这对我有用。
