Activator - 如何使用-Xlint重新编译:未选中？

Question

我使用run内部命令运行我的播放应用程序activator.当我打开索引页面时,在编译源代码后,控制台会打印出来

[warn] Note: Some input files use unchecked or unsafe operations.
[warn] Note: Recompile with -Xlint:unchecked for details.

我怎么做？如何使用该参数重新编译？我尝试用activator -J-Xlint:unchecked和运行激活器JAVA_OPTS="-Xlint:unchecked" activator,两者都导致了

Unrecognized option: -Xlint:unchecked
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Answer 1

将其添加到build.sbt:

javacOptions += "-Xlint:unchecked"
