我尝试使用命令设置 CIsbt -mem 2048 clean compile test并得到以下结果

CI 日志在这里： http: //git.brut.us/gitlabci/projects/1/builds/d274440d0de549380bc5387085055ccc749803b9
我正在尝试构建的项目是 akka 书中的示例（github 上的来源：https ://github.com/RayRoestenburg/akka-in-action/tree/master/chapter2 ）
项目本身很小，大约 5 个 scala 文件。运行它的机器有 4GB 的内存。我假设有一些 sbt 配置需要将 permsize 设置得低一点，这样它就不会消耗所有的内存（或者可能更高？）。我环顾四周，实现这一目标的方法非常不一致，我尝试了一些但没有运气。
sbt：
$ sbt -v
# Executing command line:
java
-Xms1536m
-Xmx1536m
-XX:MaxPermSize=384m
-XX:ReservedCodeCacheSize=192m
-jar
/usr/lib/sbt/sbt-launch.jar
关于：This is sbt 0.12.0
任何帮助，将不胜感激！
