如何将java库连接到项目以测试库

Question

So I need to connect a library to my repo in IntelliJ, so I can test the library as it interacts with my main project. And I got this command from a member on my team: "So you need to change .java files in entity manager (which is the library) repo and do mvn clean package to generate the jar file locally, the use that jar in your project repo. Then create dummy folder in your project with the same package name and copy those .java files from entity manager."

What does change the java files mean? What about "use that jar"? I'm so confused.

Answer 1

Use "mvn install" instead of package. This puts the library into your local .m2 repo and makes it available to your project in idea

Answer 2

If you do mvn clean package it produces a .jar file in target/ folder. Use that dependency to your project if they both share a common parent pom.xml

If you do mvn clean install it produces the jar file in target/ folder + copies the .jar file to your local m2 folder. That way you can use that .jar file to any project locally. Just use the with matching version, artifact and groupId whereever you need to use that jar file.

For both options above, you need to define sth like below in your pom.xml

 <dependency>
        <groupId>com.my.library</groupId>
        <artifactId>mylib-artifact</artifactId>
        <version>1.VERSION</version>
</dependency>

Not recommended:

• You can also put the .jar file to your project (without doing mvn clean install ) See: http://blog.gtiwari333.com/2016/12/maven-use-local-jar-without-installing.html

• Or manually add the .jar to your project as project dependency using your IDE's project configuration
