ERROR: JAVA_HOME is set to an invalid directory: /usr/lib/jvm/java-8-openjdk-amd64

I'm fairly new to Docker and am struggling with JAVA_HOME not being seen in a Dockerfile. I get the titular error; which includes Please set the JAVA_HOME variable in your environment to match the location of your Java installation. & executor failed running [/bin/sh -c /opt/Android/cmdline-tools/latest/bin/sdkmanager --update]: exit code: 1 when it runs RUN /opt/Android/cmdline-tools/latest/bin/sdkmanager --update.

I feel like I'm at a loss but I think my issue is not knowing where the JDK is being installed to or knowing how to find it from a Dockerfile; I've tried echoing JAVA_HOME thinking I could see it while the image built but, again, no luck. Any help with this would be greatly appreciated. I've been pulling my hair out Googling & trying things. Thank you.

  • In a comment, you mentioned:

    when I run [RUN ls -lart /usr/lib/jvm/java-8-openjdk-amd64], I get cannot access '/usr/lib/jvm/java-8-openjdk-amd64': No such file or directory

    Maybe I'm missing something, but... doesn't that mean that the directory does not exist?

    Either you got the path wrong, or (as another answer suggested) there's something in your Dockerfile, probably line endings, that's mangling your lines.

    To discard the bit about line endings, try the same command but switching the parameters, i.e.:

    RUN ls /usr/lib/jvm/java-8-openjdk-amd64 -lart

    If now it whines about unrecognized options, then it's probably a line ending issue (which now affects the t option instead of the directory path).
    However, if it still says No such file or directory, then you definitely should check your Java installation path.
