未能执行目标 org.codehaus.mojo:exec-maven-plugin:1.2.1:exec

Question

我需要从源代码构建 Cloudstack，并在文档中遵循 this article。但是每次我用 maven 构建它时，我都会遇到以下错误。作为一种解决方案，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。

Answer 1

最新版本的cloudstack可以在cloudstack downloads页面找到

对该版本分支执行 git checkout，然后按照您提到的 developer guide 进行操作。

如果版本为 x.y.z，则分支名称通常为 x.y

开发者指南是专门为 4.2 编写的。您可能需要根据 cloudstack 版本调整 java 包版本。

确保安装了正确的java版本

java -version 和 javac -version

cloudstack 需要 java 1.6 到 4.3，java 1.7 需要 4.4 及更高版本

Answer 2

您应该使用 4.2 标签构建，因为您遵循了提到的教程，我遇到了与该标签版本类似的问题，并最终升级到更高版本来解决此问题。

CloudStack 已经发布了 4.4 版本，应该可以解决您的问题，因此您可能需要将源更新到该标签并重试您构建的应该可以正常工作：

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