How to develop multiple maven projects with aggregation relationships in eclipse and manage them with git

How to develop multiple maven projects with aggregation relationships in eclipse and manage them with git

Maven has recently been used in development projects. Multiple maven projects are related to each other, so they are created separately and managed using maven aggregation.

The project uses git to manage code because it is set during code uploading. the gitignore file is not uploaded. setting and other files, so the maven project downloaded in git is not an elipse project file, so it is not convenient to import the code after pulling the code in github, so here we use the maven plug-in to convert each project into an Eclipse project.

 

The project structure is as follows:

Here, encryption is one of multiple maven projects that depend on the pom file in the Utils4Java-parent

Utils4Java-parent:

Encryption project (the same is true for other maven project structures created ):

Except for the pom file, other projects are not checked because they are uploaded to github using git. the gitignore file is ignored, while the src file is not uploaded because I did not add source code to the folder and it is empty. The. setting file marked by the eclipse project file is not uploaded.

 

The import in eclipse is as follows:

 

 

I. How to Use maven to manage multiple projects

The pom file for the Utils4Java-parent is as follows, and all pom files for maven projects depend on this parent file:

        ${project.organization.name}
        ${project.artifactId} 
       
        ${project.version}
        
       
        ${project.build}
        
                                          
                 
                      
   
   
   
   
       
  
  
  
  
  
    
 

The pom file in the encryption project is as follows:

 

 

 

 
  
   4.0.0
  
  
   
    com.kxw
   Utils4Java-parent
   
    0.0.1-SNAPSHOT
   
   
    ../Utils4Java-parent/pom.xml
   
  encryption
  
   jar
  
  
   encryption
  
  
   http://maven.apache.org
  
  
   
    UTF-8
   
  
  
   
    
     junit
    junit
    
     test
    
   
  
 

 

In this way, you can create multiple maven files and rely on the parent POM file.

 

2. Use git to manage project code

 

. Gitignore file:

 

.*.swp.DS_Store*target**.jar*.war*.ear*.classclasses/.svn.classes.project.classpath.settings/.metadatabintmp/**tmp/**/**.tmp*.bak*.swp*~.nib.classpath.settings/**tartget/**git.properties

3. Use maven plug-in to change the project to an eclipse project

These plug-ins have been configured in the parent POM file, and only run MavenEclipseBuild. bat.

 

cd Utils4Java-parentcall mvn eclipse:clean eclipse:eclipse pause
