I want to add "org.kohsuke" % "file-leak-detector" % "1.13" java agent to my sbt configuration.
//plugins.sbt
addSbtPlugin("com.lightbend.sbt" % "sbt-javaagent" % "0.1.5")
//build.sbt
enablePlugins(SbtWeb, PlayScala, DebianPlugin, JavaAgent)
javaAgents += "org.kohsuke" % "file-leak-detector" % "1.13"
but this failed at runtime.
Failed to find Premain-Class manifest attribute in /usr/share/someApp/bin/../file-leak-detector/file-leak-detector-1.13.jar
Error occurred during initialization of VM
agent library failed to init: instrument
I've found that i need jar with dependencies to run it as javaAgent but event if I theoretically could download it from https://repo1.maven.org/maven2/org/kohsuke/file-leak-detector/1.13/
I don't know how to use it with sbt-javaagent plugin.
I have tried also:
javaAgents += ("org.kohsuke" % "file-leak-detector" % "1.13") from "https://repo1.maven.org/maven2/org/kohsuke/file-leak-detector/1.13/file-leak-detector-1.13-jar-with-dependencies.jar"
but without luck. Any ideas how to force sbt-javaagent plugin to use file-leak-detector-1.13-jar-with-dependencies.jar instead of file-leak-detector-1.13-jar?
I think you are doing the right thing using from to provide explicit URL
If your project requires a dependency that is not present in a repository, a direct URL to its jar can be specified as follows:
libraryDependencies += "slinky" % "slinky" % "2.1" from "https://slinky2.googlecode.com/svn/artifacts/2.1/slinky.jar"
It seems to work on my machine when I provide explicit scope like so
javaAgents += JavaAgent(
"org.kohsuke" % "file-leak-detector-1.13-jar-with-dependencies" % "1.13" % Runtime from "https://repo1.maven.org/maven2/org/kohsuke/file-leak-detector/1.13/file-leak-detector-1.13-jar-with-dependencies.jar",
arguments = "help"
)
Note % Runtime. I think it works because arguments = "help" is honoured and sbt run outputs
