I am building a Java project in Jenkins, inside a Docker container. The build is working fine. However, I realized that the image I'm using is a jdk21-headless (Amazon correctto 21 headless) image, which doesn't have javac. How can Gradle build it without javac?

By default, Gradle uses the JavaCompiler API. I.e. it calls the compiler from within a running JVM through the API. The

javac

command ist not used (unless you explicitly configure the compiler task to use one).

Thank you for the answer. That explains
