问题
I am running my fat jar with command java -Djava.security.krb5.conf=/krb5.conf -jar my.jar.
How to run my app with this option via sbt?$ sbt -Djava.security.krb5.conf="module\\src\\main\\resources\\krb5.conf" run doesn't work. Error:
ctl-scala>sbt -Djava.security.krb5.conf="ctl-core\src\main\resources\krb5.conf" ctl-ui-backend/run
Warning: invalid system property 'java.security.krb5.conf'

回答1:
Can you try sbt -J-Djava.security.krb5.conf="module/src/main/resources/krb5.conf" run
The -J causes the sbt launcher to pass those as options to the JVM.
回答2:
As sbt manual it will pass JAVA_OPTS environment variable to the java and if you can not set the variable .jvmopts will hold the java commandline arguments. so if you are in bash :
export JAVA_OPTS="-Djava.security.krb5.conf=/krb5.conf"
before sbt command will pass the argument to java runtime.

Have a look at one of my project where I pass in command line arguments via sbt:

I guess your double quotes is messing it up! Try it without them!
