Hadoop 2.4 maven build OutOfMemoryError：Java堆空间

Question

我试图在我的Mac上构建完整的Hadoop源代码。当我尝试构建时，我经常遇到错误：“Java.lang.OutOfMemoryError：Java堆空间”。我尝试使用命令export maven_opts=“-xms256m-xmx1024m”和export maven_opts=“-xmx2g-xx:maxpermsize=512m-xx:reservedcodecachesize=512m”设置maven选项。但这些解决方案都没有帮到我。我有一个4GB DDR3内存。2.3GHz英特尔酷睿i5处理器。请给我提供正确的方向。日志：

谢谢和问候。

Answer 1

这个错误是由maven编译器插件抛出的，编辑您正在构建的pom文件，属性maven-compiler-plugin add below configuration下

 <configuration>
 <verbose>true</verbose>
 <fork>true</fork>
 </configuration>

这将清除堆空间错误。
