怎么乱码了 : (   重新在发一遍吧

碰到一个非常奇怪的问题，我使用maven-3.11来进行release:prepare打包失败，并报空指针 异常。降级到maven-3.0.5来做同样的事情，则成功通过，难道是maven-3.11需要有什么特别要注意的事情吗？

大家有没有碰到同样的事情？

我的maven信息如下：

# mvn -v
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 23:22:22+0800)

OS name: "linux", version: "2.6.18-164.el5", arch: "amd64", family: "unix"

执行的命令如下：

# mvn release:clean release:prepare -DautoVersionSubmodules -T 10 -DdryRun -X

复制了错误信息如下:

我看到你第一次发的不是乱码。

你对比一下 release 插件的版本看看：

$ mvn release:help | grep maven-release-plugin

[INFO] --- maven-release-plugin:2.0:help (default-cli) @ xxx ---

[INFO] org.apache.maven.plugins:maven-release-plugin:2.0

刚刚测试了一下，还是不行啊

[Sutra Zhou]

那也可以试试 maven 3.0.5 默认的 maven-release-plugin:2.0 啊。反正是可以在 pom.xml 里指定 plugin 版本的。
