Maven project not being treated as Java in Eclipse

Question

I\'m working on a project that has lots of different Maven projects. I\'ve been doing a bunch of JUnit testing on these projects, and usually this goes well. I open up Eclipse

Answer 1

There are two ways this can be achieved.

1) By Changing the project nature. Right-click on Project -> Properties -> Project Natures, then choose all natures that apply for your case (e.g. java).

(OR)

2) By updating the .project file and add all the natures that are required for the project. This .project file is located at the root folder of the project. If the file does not exist for any reason, create a new file, and add the sections for each nature that is required e.g., as follows.

        yourprojectName
        
        
        
        
                
                        org.eclipse.jdt.core.javabuilder
                        
                        
                
                
                        org.eclipse.wst.common.project.facet.core.builder
                        
                        
                
                
                        org.eclipse.m2e.core.maven2Builder
                        
                        
                
        
        
                org.eclipse.wst.common.project.facet.core.nature
                org.eclipse.jdt.core.javanature
                org.eclipse.m2e.core.maven2Nature
