Add LCM into gradle

[Joechencc]

I want to import LCM message in gradle, I moved lcm.jar into the lib/ folder in root directory and change setting.gradle to the following. I wonder why that is not working. ERROR: The import lcm cannot be resolved.

buildscript {
repositories {
maven { url "https://plugins.gradle.org/m2/" }
mavenLocal()
flatDir {
dirs 'lib'
}
}
dependencies {
}
}

compile name: 'lcm'
