“src / main / java”约定的优点是什么？ [英] What is the advantage of the 'src/main/java'' convention?

问题描述

我注意到很多专案都有以下结构：

I've noticed that a lot of projects have the following structure:

• Project-A
  
  
  
  
  • bin
  
  
  • lib
  
  
  • src
    
    
    
    
    • main
      
      
      
      
      • java
        
        
        
        
        • RootLevelPackageClass.java
        
        

        我目前使用以下约定（因为我的项目是100％java）：

        I currently use the following convention (as my projects are 100% java):

        
        
        • Project-A
          
          
          
          
          • bin
          
          
          • lib
          
          
          • src
            
            
            
            
            • RootLevelPackageClass.java
            
            

            我目前不使用Maven，但我想知道这是否是一个Maven约定，或者如果有另一个原因。

            I'm not currently using Maven but am wondering if this is a Maven convention or not or if there is another reason. Can someone explain why the first version is so popular these days and if I should adopt this new convention or not?

            推荐答案

            主要好处是将 test 目录作为 src 与 main 中的目录结构具有相同的目录结构：

            Main benefit is in having the test directory as subdirectory of src with the same directory structure as the one in main:

            
            < A
            
            
            
            
            • bin
            
            
            • lib
            
            
            • src
              
              
              
              
              • main
                
                
                
                
                • java
                  
                  
                  
                  
                  • RootLevelPackageClass.java
                  
                  
                  
                  
                  • java
                    
                    
                    
                    
                    • TestRootLevelPackageClass.java
                    
                    

                    RootLevelPackageClass 的所有包私有方法都将可见， TestRootLevelPackageClass 。由于测试代码也是源代码，它的位置应该在 src 目录下。

                    All package private methods of RootLevelPackageClass will be visible, i.e. testable from TestRootLevelPackageClass. Since the testing code is also source its place should be under src directory.
