java 无法执行目标 org.codehaus.mojo:exec-maven-plugin:1.2.1:exec

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec

提问by Deepal

I needed to build Cloudstack from source and followed this articlein the documentation. But everytime I built it with maven, I got stuck with following error. Guessing as a solution, I tried this build with oracle jdk-8, openjdk-7 and openjdk6. And also tried tomcat6 and tomcat8. But got no solution. What is going wrong? I think the reason could be a problem with a plugin but have no idea how to solve. I searched online for this error, but got no workaround.

我需要从源代码构建 Cloudstack，并按照文档中的这篇文章进行操作。但是每次我用 maven 构建它时，我都会遇到以下错误。猜测作为解决方案，我尝试使用 oracle jdk-8、openjdk-7 和 openjdk6 构建此版本。并且还尝试了 tomcat6 和 tomcat8。但没有得到解决。出了什么问题？我认为原因可能是插件的问题，但不知道如何解决。我在网上搜索了这个错误，但没有解决方法。

The developer guide is specifically written for 4.2. You may have to adjust the java packages version according to cloudstack version.

You should be using the 4.2tag build since you followed the mentioned tutorial, I have run into a similar issue with that tag version and ended up upgrading to an onward version to resolve the case.

自从您遵循上述教程以来，您应该使用4.2标记构建，我遇到了与该标记版本类似的问题，最终升级到更高版本以解决此问题。

CloudStackhas already release the 4.4version which should resolve you problem, so you may need to update your sources to that tag and retry you build which should work without problems:

CloudStack已经发布了应该可以解决您问题的4.4版本，因此您可能需要将源更新为该标签并重试构建，这应该可以正常工作：

$ git fetch origin && git checkout -b 4.4.0 tags/4.4.0
$ mvn clean install -Pdeveloper,systemvm
