@stefanxinhong 麻烦您检查一下JRE System Library默认加入的是否是JRE，如果是JRE，需要把JRE替换为JDK。如图所示为替换后的JDK：

[stefanxinhong]

@sinllychen 修改过后还是不行，截图如下

@stefanxinhong 您好，上述方式在windows系统上测试过是没问题的。看了下您的JDK路径，您这个应该是在linux或者centos系统下吧。在linux系统下的我们倒是没有测试过。不确定行不行。这个问题可能需要您那边自己看下了。你的Linux系统有JAVA_HOME的环境变量吗？

顺带问下您用的是idea还是eclipse编译器呢？

[sinllychen]

@stefanxinhong 如果是IDEA编译器，请把那个tools的dependency注释掉就行了。

[stefanxinhong]

@sinllychen
使用的是linux系统，eclipse编译器，JAVA_HOME的环境变量是有的，现在搞不清楚问题出现在什么地方，如果在windows测试是没有问题的，我就换一下系统试一下

@sinllychen 在windows10下，进行到gwt:compile步报错，log信息如下

使用的是linux系统，eclipse编译器，JAVA_HOME的环境变量是有的，现在搞不清楚问题出现在什么地方，如果在windows测试是没有问题的，我就换一下系统试一下

linux 下的eclipse在debug configgurations下的maven build 菜单下的构建项的environment中添加一个JAVE_HOME对应的路径就好

什么意思呢？我也时centos,eclipse,也遇到这个问题了
