How can a Maven Project become a Java Project ? [message #769192]

Hi everyone,

I have a Maven project in Eclipse but it doesn't recognize anything linked to Java at all. For instance, when I write code and I make a mistake, it doesn't underline in red. Or when I want to do "New/Class" to add a Java file, well...I don't have this option anymore. Just "File"...

Does anybody know what I should do so that my Maven project can be also recognized as a "Java project" ?

Thank you in advance!

You have to ensure that the Java file is in a source tree specified in the "Source" tab in the "Java Build Path" section of your project preferences.

I'm not sure how to interpret your statement about not having "New/Class" anymore. I don't know what you mean there.

Thanks for your answer David.

Unfortunately, there is no "Java Build Path" in the project preferences. I know what you mean cos I can find it in a normal Java Project, but not in my current project.
By "new/class", i meant: in a Java project, when you want to create a new Class and add it to your project, you right click on your project in the project explorer, choose "New..." and then "Class". So in my project right now, there's no "Class" option in the "New..." menu.

I had a feeling you would say that.

When I've been in a similar situation, it was time for some manual surgery on the ".project" file. If you have a Maven Java project that appears to be fine, then open up its ".project" file and compare it to the one with the problem. There will likely be "buildSpec" or "nature" elements in the good project that are not in the other. Simply copy those missing elements from the good one to the bad one. If you're not experienced with modifying this file, you should make a copy somewhere out of your workspace first. After you save the file, you should get closer to what you need.
