Gradle Cheat Sheet

Include details on which test that failed?

By default, gradle doesn't provide much information on which test that failed. This is something you can easily configure. Add the following configuration:

  test {
    useJUnitPlatform()
    afterTest(
      KotlinClosure2({ desc: TestDescriptor, result: TestResult ->
        if(result.resultType == TestResult.ResultType.FAILURE) {
          println("❌ Test failed 👉 ${desc.className} > ${desc.displayName}")
          result.exception?.printStackTrace()
        }
      })
    )
  }

Skip all withType<>{} during build/tests in Idea?

If you have a fancy configuration with Gradle with sections with things being triggering on types or stages, there might be a possibility that whenever you trigger (something) in Intellij, things may be über-slow as everything needs to happen before your (whatever) starts up. To "fix" this, do the following:

Just pop in to

settings > Build (..) > Build Tools > Gradle

and do the following:

• Build/Test using => IntelliJ
• Run tests using => IntelliJ

Done ✅👌

Versions? Use this!

object Version {
  const val javaVersion = "16"
  const val kotlinVersion = "1.4.32"
  const val testContainers = "1.15.3"
}

Used by e.g:

..
  implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:${Version.kotlinVersion}")
  implementation("org.jetbrains.kotlin:kotlin-reflect:${Version.kotlinVersion}")
..

Assemble git hash

Add this to the top of your class.

import java.io.ByteArrayOutputStream
...
class Git {
  val gitAbbriv = "git rev-parse --verify --short HEAD".runCommand()
  val gitBranch = "git rev-parse --abbrev-ref HEAD".runCommand()
  val gitUsername = "git config user.name".runCommand()
  val gitLastCommitDateTime = "git log -1 --format=%cd".runCommand()
  private fun String.runCommand(workingDir: File = project.rootDir): String =
    ByteArrayOutputStream().use {
      try {
        project.exec {
          this.workingDir = workingDir
          commandLine = [email protected](" ")
          standardOutput = it
        }
        println("Executed command: $this")
        String(it.toByteArray()).trim()
      } catch (e: Exception) {
        println("Command failed: $this. Using fallback (-)")
        "-"
      }
    }
}
}
