Question

我需要修改KIE Workbench源码，我有两个问题阻止我使用Maven 3.2.5构建，一个在Windows上，一个在Linux上。

在Windows 7上，我收到错误消息

[deletia...]SNAPSHOT\uberfire-backend-api-0.4.0-SNAPSHOT-sources.jar,
com.google.gwt.dev.Compiler,-logLevel, INFO, -style, OBF, -war, 
c:\kie-wb-webapp\target\kie-wb-webapp-6.1.1-SNAPSHOT, -localWorkers, 1,
-strict, -XfragmentCount, -1, -deploy, c:\kie-wb-webapp\target\gwt-symbols-deploy, -gen, 
c:\kie-wb-webapp\target\.generated, org.kie.workbench.FastCompiledKIEWebapp]: 
Error while executing process. Cannot run program "c:\development\software\jdk\jdk1.7.0_71\jre\bin\java": 
CreateProcess error=206, The filename or extension is too long.

所以我查了一下，显然，这是众所周知的限制，因为gwt-maven-plugin会创建一个超过8191个字符的命令行，这是禁止的。所以我试了一下Ubuntu。

在Ubuntu上，

我得到了：

[INFO] --- gwt-maven-plugin:2.5.1:compile (gwt-compile) @ kie-wb-webapp     [ERROR] Java HotSpot(TM) 64-Bit Server VM warning: ignoring option     MaxPermSize=256m; support was removed in 8.0

[INFO] BUILD FAILURE*

我找到一个或两个问题的解决办法非常重要（我的猜测是，如果我在Windows上清除命令行问题，我将再次遇到番石榴问题）。此外，除非绝对必要，否则我无法升级到6.2.x，因为这会为我的项目带来很多工作。

有没有人碰到这个？

If you don't need Java 8 support, you may be able to solve the problem by using an earlier version of the JDK. I believe that you do this by setting JAVA_HOME for your Maven run. You can download a JDK 7 here.

You could also build Guava yourself from HEAD, as the problem has been fixed there but not included in a release. Or you could wait for a 19.0-rc1, which we hope to have out soon.

无法构建kie-wb-webapp 6.1.x（JBPM）
