How to include local jar files in Maven project [duplicate]

Although it works to use the systemPath reference, it is better to create a local repository. And fortunately, it is easy to do.

Creating a local repository holding jars not available in a public repository

NOTE: I use Eclipse, so some of the instructions are specific to Eclipse. Most are easily generalizable.

Assumptions

• The jar was created by Maven in another project with the following…

  <groupId>com.foo</groupId>
  <artifactId>test</artifactId>
  <version>0.1.1</version>
  <packaging>jar</packaging>
  

---

In Project (that wants to access the jars)

• Create repo directory just off the project base directory
• For each jar to be accessed locally…
  • add directories for each level of the groupID (ex. /repo/com/foo)
  • add jar name (aka artifactId) without the version (ex. /repo/com/foo/test)
  • add directory for the version of the jar (ex. /repo/com/foo/test/0.1.1)
  • put the jar in that directory (ex. /repo/com/foo/test/0.1.1/test-0.1.1.jar)

In pom.xml (for the project that wants to access the jars)

• Define the local repository

  <repositories>
    <repository>
      <id>data-local</id>
      <name>data</name>
      <url>file://${project.basedir}/repo</url>
    </repository>
  </repositories>
  

• Add the dependency on the local jar. From our example above, this would be…

  <dependency>
    <groupId>com.foo</groupId>
    <artifactId>test</artifactId>
    <version>0.1.1</version>
  </dependency>

Rebuild

• Rt click pom.xml -> Run as -> Maven build
