当我使用SBT打包Scala项目时，我遇到以下问题：
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
[info] Loading project definition from D:\marathon-master\project
Version '20170916T025229' is not fully supported, please update the git tags.
[info] Set current project to marathon (in build file:/D:/marathon-master/)

java.lang.RuntimeException: Library cannot be resolved: D:\marathon-master\docs\docs\rest-api\public\api\appContainer.raml -- D:\marathon-master\docs\docs\rest-api\public\api\v2/types/app.raml [line=6, col=17]

app.raml中的5-7行代码就像那样：
uses:
appContainer: appContainer.raml
artifact: artifact.raml
app.raml和appContainer.raml的目录是＆＃34; D：\ marathon-master \ docs \ docs \ rest-api \ public \ api \ v2 / types /＆＃34;都。所以我改变了6行的app.raml：
appContainer: v2/types/appContainer.raml
但是，当我运行＆＃34; sbt package＆＃34;再一次，警告出现了：
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m;
support was removed in 8.0

为什么会有此警告？有什么想法吗？
