3. Add the maven project jar to the maven repository. The Mave project depends on another Maven project.

1. If you want maven projects to depend on another maven project, the dependent project must have corresponding jar packages in the maven repository. Therefore, you must execute the mvninstall command on the dependent project. 2. Create the HelloFriend directory of the second project module and the agreed directory structure vcmRlcj01cellspacing0cellpadding0HelloFriend -- src ----

2. Create the HelloFriend directory of the second project module and the agreed directory structure

VcmRlcj0 = "1" cellspacing = "0" cellpadding = "0">

HelloFriend -- Src ----- Main ---------- Java ---------- Resources ----- Test --------- Java --------- Resources -- Pom. xml

3. Create pom. xml in the HelloFriend root directory of the project.

4.0.0 Cn. toto. maven HelloFriend 0.0.1-SNAPSHOT HelloFriend Junit Junit 4.9 Test Cn. toto. maven Hello 0.0.1-SNAPSHOT Compile

4. Create the HelloFriend. java file in the src/main/java/cn/toto/maven directory.

Package cn. toto. maven; Import cn. toto. maven. Hello; Public class HelloFriend { Public String sayHelloToFriend (String name ){ Hello hello = new Hello (); String str = hello. sayHello (name) + "I am" + this. getMyName (); System. out. println (str ); Return str; } Public String getMyName (){ Return "John "; } }

5. Create the test file HelloFriendTest. java in the/src/test/java/cn/toto/maven directory.

Package cn. toto. maven; Import static junit. framework. Assert. assertEquals; Import org. junit. Test; Import cn. toto. maven. Hello; Public class HelloFriendTest { @ Test Public void tesHelloFriend (){ HelloFriend helloFriend = new HelloFriend (); String results = helloFriend. sayHelloToFriend ("tuzuoquan "); AssertEquals ("Hello tuzuoquan! I am John ", results ); } }

6. Run the mvn command in the HelloFriend directory (note the HelloFriend folder)

7. Run the mvnpackage command again in the HelloFriend directory.
