Java 构建Spark 1.5.2-Maven堆空间问题

我正在使用

makedistribution.sh

脚本构建ApacheSpark。直到

spark-streaming-mqtt_2.10

模块运行正常。 我的

MAVEN_OPTS

环境变量是：

export MAVEN_OPTS="-Xmx15g -XX:MaxPermSize=15000M -XX:ReservedCodeCacheSize=15000M"

即使分配给Maven的内存非常高，它仍然无法创建

spark-streaming-mqtt-test-1.5.2.jar

jar文件

以下是错误跟踪：
