java - 无法执行目标 org.codehaus.mojo :exec-maven-plugin:1. 2.1:exec

Question

我需要从源代码构建 Cloudstack 并遵循 this article在文档中。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，我用 oracle jdk-8、openjdk-7 和 openjdk6 尝试了这个构建。并且还尝试了tomcat6和tomcat8。但是没有解决办法。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，但没有找到解决方法。

Answer 1

最新版本的cloudstack可以从cloudstack downloads找到页面

对该版本分支执行 git checkout，然后遵循 developer guide你提到过。

如果版本是 x.y.z，分支名称通常是 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 4.3，4.4 及以上需要 java 1.7
