问题：无法建立使用与詹金斯JDK 1.8Maven的詹金斯无法找到在JDK中的javac编译
说明春天Maven项目：进出口使用詹金斯建立由Maven.I有管理我的春天项目使用JDK安装选项在Jenkins中配置Java 1.7和1.8。当在构建配置中选择Java 1.7并运行构建时，构建过程就会成功。但是当我在构建配置中选择Java 1.8并运行构建时，构建过程失败。
****下面是詹金斯控制台输出****

我也跑了Maven的与Java 1.7和没有任何问题observerd手动。但是 当我跑一样与Java 1.8和重定向输出到文件， 发现下面的错误

JAVA_HOME变量被正确地指向JDK 1.8安装主目录和bin文件夹也被添加到该路径
回波％JAVA_HOME％结果在C：\ devenv的\ PROGRAMFILES \爪哇\ jdk1.8.0_20
瓦时恩改变了JAVA_HOME变量指向的Java 1.7，建立正常运行，没有错误
的完整路径只是为了消除任何疑问，也确实是下'C安装了JDK：\ devenv的\ PROGRAMFILES \的Java \ jdk1.8.0_20'并指出当' JAVA_HOME'，运行'javac -version'会产生正确的结果，对吗？ – Morfic
是的。运行命令C：\ Users \ anonymous> javac -version 结果输出 - > javac 1.8.0_20 – kavsik
经过几个小时的调试后，maven获取了tools.jar来启动Sun的Main类，获得了成功（使用JDK 1.7）和失败（使用JDK 1）的自定义日志输出。8）构建运行如下 – kavsik
