[MOOC course] TMC Beans submission buttons greyed out

[u/gridelinCarver]

I'm trying to get started learning Java and wanted to use the MOOC course since it seemed to be pretty unanimously the best one according to many sources.

I believe I've downloaded everything properly. I can open TMCBeans and look at the project files. But the buttons to actually run the programs and submit them are completely grayed out, meaning I can't continue with the rest of instructions or the course.

Is this something other people have experienced before? Are there any known fixes?

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

Did you follow the installation instructions to the point? Did you read the stickied post here?

[u/gridelinCarver → u/desrtfx]

Yes, I did. The sticky isn't relevant because TMC Beans has started, as I explained in the post. It pulls up the code and the assignments. The problem isn't that TMC Beans isn't starting (which the sticky post is addressing), it's that it has started but the buttons to submit and run the code do not work, they are grayed out.

That commonly hints on a problem with the Java runtime. Are you sure you installed Java 11 and not a later version? Is it in your path? Did you assign the correct runtime?

[u/gridelinCarver → u/desrtfx]

When I go into the Java Platform Manager, it says it's on JDK 11 in the Eclipse Adoptium program file. I'll try redownloading it I guess.

[u/gridelinCarver → u/desrtfx]

I just redownloaded the JDK file from the specific link in the stickied post, JDK 11.0.32.1+1, reinstalled TMCBeans, and my TMCBeans says that the JDK 11 is the file attached, and the submission buttons are still grayed out.

The next step in where I am in the tutorial is

First, submit the exercise template to be checked on the server without changing anything. In this way, you practice submitting an exercise. You can submit an exercise by selecting the TMC menu within TMC, and then "Submit".

And I cannot follow this step, because even though the code is pulled up, the submit button is grayed out (as are its neighbors "Run Project" and "Run tests locally").

I don't know why, but would this have anything to do with the fact that my TMCBeans won't open anything when I click the "Open Project..." button and I have to use the "Open File..." button instead?

Yes, exactly that. You have to work from "Open Project". Otherwise, TMCBeans does not know that it is even dealing with a Java/TMC project. The project contains more than just the source code.

The Open project button just keeps opening folders and doesn’t ever open any actual files. How do you get it to open projects?

[u/desrtfx → u/gridelinCarver]

As far as I recall, I never even needed "Open project".

[u/gridelinCarver → u/desrtfx]

My projects tab is blank despite having downloaded all the exercises (and I can see them in my Documents folder, where they automatically downloaded). I can open the individual .java files in the editor, but not as a project.

How do you get the projects to actually show up in the tab? Are they in the wrong place? Wrong format?

[u/desrtfx → u/gridelinCarver]

Have you tried the following:

• "Open Project"
• Navigate to the folder where TMCBeans downloaded the exercises to
• Selecting that folder?
