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.

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，，，，
