How do I add a project as a dependency of another project?

January 20, 2023 by Tarik

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so <project> … <dependencies> <dependency> <groupId>yourgroup</groupId> <artifactId>myejbproject</artifactId> <version>2.0</version> <scope>system</scope> <systemPath>path/to/myejbproject.jar</systemPath> </dependency> </dependencies> … </project> That said it is usually the better (and preferred … Read more

maven dependency without version

January 17, 2023 by Tarik

Ok, I think I’m gonna answer it myself. Of course I took a look at dependency:tree, but all the dependencies that I mentioned were first-level members of the tree. What I failed to notice right away, is that dependencyManagement is not present in the parent, but it is however present in the submodules, and what … Read more

‘dependencies.dependency.version’ is missing error, but version is managed in parent

January 16, 2023 by Tarik

If anyone finds their way here with the same problem I was having, my problem was that I was missing the <dependencyManagement> tags around dependencies I had copied from the child pom.

Maven Out of Memory Build Failure

January 14, 2023 by Tarik

What kind of ‘web’ module are you talking about? Is it a simple war and has packaging type war? If you are not using Google’s web toolkit (GWT) then you don’t need to provide any gwt.extraJvmArgs Forking the compile process might be not the best idea, because it starts a second process which ignores MAVEN_OPTS … Read more

m2e error in MavenArchiver.getManifest()

January 5, 2023 by Tarik

I encountered the same issue after updating the maven-jar-plugin to its latest version (at the time of writing), 3.0.2. Eclipse 4.5.2 started flagging the pom.xml file with the org.apache.maven.archiver.MavenArchiver.getManifest error and a Maven > Update Project.. would not fix it. Easy solution: downgrade to 2.6 version Indeed a possible solution is to get back to … Read more

MAVEN_HOME, MVN_HOME or M2_HOME [duplicate]

January 2, 2023 by Tarik

I’ve personally never found it useful to set M2_HOME. What counts is your $PATH environment. Hijacking part of the answer from Danix, all you need is: export PATH=/Users/xxx/sdk/apache-maven-3.0.5/bin:$PATH The mvn script computes M2_HOME for you anyway for what it’s worth.

How to override maven property in command line?

December 31, 2022 by Tarik

See Introduction to the POM finalName is created as: <build> <finalName>${project.artifactId}-${project.version}</finalName> </build> One of the solutions is to add own property: <properties> <finalName>${project.artifactId}-${project.version}</finalName> </properties> <build> <finalName>${finalName}</finalName> </build> And now try: mvn -DfinalName=build clean package

Maven: Lifecycle vs. Phase vs. Plugin vs. Goal [closed]

December 18, 2022 by Tarik

A Maven lifecycle is an (abstract) concept that covers all steps (or better: all the steps the Maven designers decided to support) that are expected to occur in a project’s development lifetime. These steps (or stages) are called phases in Maven terminology. A Maven plugin is a container for/supplier of goals. Code implemented in goals … Read more

Run a single Maven plugin execution?

December 18, 2022 by Tarik

As noted in How to execute maven plugin execution directly from command line?, this functionality has been implemented as MNG-5768, and is available in Maven 3.3.1. The change will: extend direct plugin invocation syntax to allow optional @execution-id parameter, e.g., org.apache.maven.plugins:maven-remote-resources-plugin:1.0:process@executionId. So, as long as you give your execution an id: mvn sql:execute@specific-execution-id uses the … Read more

How to access maven.build.timestamp for resource filtering

December 17, 2022 by Tarik

I have discovered this article, explaining that due to a bug in maven, the build timestamp does not get propagated to the filtering. The workaround is to wrap the timestamp in another property: <properties> <timestamp>${maven.build.timestamp}</timestamp> <maven.build.timestamp.format>yyyy-MM-dd HH:mm</maven.build.timestamp.format> </properties> Filtering then works as expected for buildTimestamp=${timestamp}
