Eclipse loops endlessly: Invoking 'Maven Project Builder'

Question

Ugh! My Eclipse is stuck in an endless loop:

• No operations to display at this time
• Refreshing Workspace Building
• Workspace. Invoking \'Maven Pro

Answer 1

The problem can be a code generating plugin like the openapi-generator-maven-plugin or the protoc-jar-maven-plugin. Such plugins are generating code that retriggers the eclipse compilation. A solution to prevent this behavior could be to disable the plugin for the Eclipse "Maven Project Builder". This can be done by adding an entry to the pom.xml like described here: https://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html

    
        
            org.eclipse.m2e
            lifecycle-mapping
            1.0.0
            
                
                    
                        
                    
                
            
        
    

Such Plugin configuration could look like similar to the following example:

  
    org.openapitools
    openapi-generator-maven-plugin
    [0.0,)
    
      generate
    
  
  
    
  

Alternatively such settings could be done globally for a eclipse workspace: Window > Preferences > Maven > Lifecycle Mappings. More about this topic can be read here: https://www.benchresources.net/eclipse-maven-plugin-execution-not-covered-by-lifecycle-configuration/
