I've installed the necessary items to make it but still to no avail.

# 答案1
**得分**: 1
问题出在这条日志信息中（看最后一行！）
> 错误组装WAR：创建WAR时出现问题：执行异常：Java堆空间
在通过 *mvn clean install* 触发构建之前，在相同的 shell/terminal 中执行以下命令：
export MAVEN_OPTS="-Xmx2048m -XX:MaxPermSize=128m"
这将允许Maven在构建阶段使用更多的RAM - 最多达到2048MB。如果不起作用，您可以进一步增加此值，以查看是否构建通过。请记住，您的机器/工作站需要有足够的空闲物理RAM。否则，构建显然会再次失败。

The problem lies in this log message (see last line!)
> Error assembling WAR: Problem creating war: Execution exception: Java heap space
**Before** triggering the build via *mvn clean install*, issue the following command in the same shell/terminal:
export MAVEN_OPTS="-Xmx2048m -XX:MaxPermSize=128m"
It will allow Maven to use more RAM - here up to 2048 MB - during the build phase(s). If it does not work, you can increase this value even further to see if the build passes. Keep in mind that your machine/workstation has needs that amount of free, physical RAM. Otherwise, the build will obviously: fail again.
