遇到的报错

sbt工具被墙的问题

请看我的上一篇文章：
关于sbt构建工具国内无法使用的问题

缺少nodejs

[info] Wrote /opt/kafka-manager/target/scala-2.11/kafka-manager_2.11-1.3.3.22.pom
Warning: node.js detection failed, sbt will use the Rhino based Trireme JavaScript engine instead to run JavaScript assets compilation, which in some cases may be orders of magnitude slower than using node.js.

[root@iZj6c5bdyyg7se9hbjaakuZ kafka-manager]#

安装nodejs

yum install -y nodejs

JDK无法分配内存（未解决）

后来查看是我的内存的确占满了，，不了解java的内存限制导致的
直接修改sbt启动文件，限制内存占用就可以了

[root@iZj6c5bdyyg7se9hbjaakuZ sbt]# cat sbt 
SBT_OPTS="-Xms256M -Xmx256M -Xss256K -XX:CompressedClassSpaceSize=128m -XX:MetaspaceSize=200m -XX:MaxMetaspaceSize=200m"
java $SBT_OPTS -jar /usr/share/sbt/bin/sbt-launch.jar "$@"
[root@iZj6c5bdyyg7se9hbjaakuZ sbt]# 

具体java的JVM参数调整还需各位自行解决，我也不太懂
后来我干脆换了个大内存机器解决了问题，，，，
