Method finalJar

sdk/java/runtime/main.go:351–370

finalJar will return the jar corresponding to the user module built In order to have the final container as minimal as possible, we just want to be able to run a jar. To make it easy, we will rename the jar as module.jar But that's not easy, as we don't know the name of the built jar, so we will ask

(
	ctx context.Context,
	ctr *dagger.Container,
)

// But that's not easy, as we don't know the name of the built jar, so we will ask maven to give us the
// artifactId and the version so we can get the jar name
func (m *JavaSdk) finalJar(
	ctx context.Context,
	ctr *dagger.Container,

	artifactID, err := ctr.
		WithExec(m.mavenCommand("mvn", "org.apache.maven.plugins:maven-help-plugin:3.2.0:evaluate", "-Dexpression=project.artifactId", "-q", "-DforceStdout")).
		Stdout(ctx)
	if err != nil {
