How to reference a local repository in maven?

Question

I downloaded the source and built caliper like this:

mvn eclipse:configure-workspace eclipse:eclipse install

Now the /target folder has:

caliper-1.0-beta-SNAPSHOT-all.jar     generated-sources                     surefire
caliper-1.0-beta-SNAPSHOT-sources.jar generated-test-sources                surefire-reports
caliper-1.0-beta-SNAPSHOT.jar         maven-archiver                        test-classes
classes                               maven-status

Now in my spring mvc application's pom file, how do I reference this local repository that I just installed?

I was referencing caliper using a dependancy like this:

   <dependency>
        <groupId>com.google.caliper</groupId>
        <artifactId>caliper</artifactId>
        <version>${caliper-version}</version>
        <scope>test</scope>
    </dependency>

But as per my last question I was advised to build from source to get an update that isn't published yet: Caliper test using exec-maven-plugin is saying main method signature isn't valid

So I am not sure how to reference this caliper version that I built locally and installed using maven.

Answer 1

If version is eg 1.0-SNAPSHOT then place the jar here

localrepo_folder
  com
     google
        caliper
           caliper  <-- artifact
               1.0-SNAPSHOT
                    caliper-1.0-SNAPSHOT.jar

By invoking mvn install, you installed the project into your local repository. Maven will use the local artifacts, in case they are available. Please note, the /target folder is not the local repository!

Have a look at

• ~/.m2/repository on Linux/Mac
• Something like C:\Documents and Settings\{your-username}\.m2\repository on Windows.

You can have a look there, if the jar is available in the folder com/google/caliper/caliper/1.0-BETA-SNAPSHOT/

So if you correctly have build and installed the caliper artifact, you can reference it in your project and maven will resolve it from your local repository. If it is not available there, it will try to resolve it from Maven central or repositories you have configured.

Be sure to check that the version of caliper is correctly referenced in your project pom, if I understand you correctly, this would mean: 1.0-beta-SNAPSHOT. It seems that you use a variable ${caliper-version}, double check if this variable is defined correctly and references the correct version.
