Maven “versions” plugin – how to exclude alpha/beta versions from response?

September 13, 2023 by Tarik

You can configure the versions plugin like this: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>versions-maven-plugin</artifactId> <version>2.1</version> <configuration> <rulesUri>someUrl</rulesUri> </configuration> </plugin> someUrl can also be a file URL. The syntax of the rules file is given in http://www.mojohaus.org/versions-maven-plugin/version-rules.html, it may contain something like this: <ruleset comparisonMethod=”maven” xmlns=”http://mojo.codehaus.org/versions-maven-plugin/rule/2.0.0″ xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=”http://mojo.codehaus.org/versions-maven-plugin/rule/2.0.0 http://mojo.codehaus.org/versions-maven-plugin/xsd/rule-2.0.0.xsd”> <ignoreVersions> <ignoreVersion type=”regex”>.*-beta.</ignoreVersion> <ignoreVersion type=”regex”>.*_ALPHA</ignoreVersion> </ignoreVersions> </ruleset>

What is the use of pom.xml in Maven?

September 5, 2023 by Tarik

In short the pom.xml will have all information to build your project. For example you want to build a project and you have only the pom.xml sent to you via mail. If there are enough entries in the pom.xml then that is all you need! You can import it to Eclipse, Maven will download your … Read more

How do I create a new packaging type for Maven?

September 1, 2023 by Tarik

To do as you described, create a Maven project with packaging jar (as stated here, as there won’t be mojo definitions). In the src/main/resources/META-INF/plexus sub-folder create a components.xml with the following contents (assuming you want the packaging type to be “my-custom-type”, change it to “foobar” if you wish). <component-set> <components> <component> <role>org.apache.maven.lifecycle.mapping.LifecycleMapping</role> <role-hint>my-custom-type</role-hint> <implementation> org.apache.maven.lifecycle.mapping.DefaultLifecycleMapping … Read more

Difference between Maven source plugin jar and jar-no-fork goal?

August 31, 2023 by Tarik

My interpretation: the jar goal is meant to be run from the command line (mvn source:jar), the jar-no-fork is meant to be bound to the lifecycle. If you look at the docs for the jar goal the key phrase is “Invokes the execution of the lifecycle phase generate-sources prior to executing itself.” If you configure … Read more

Maven archetype plugin doesn’t let .resources in archetype-resources through

August 28, 2023 by Tarik

The bug seems to be still present in the maven-archetype-plugin v3.0.1 . For those who do not want to downgrade the maven-resource-plugin. I managed to establish a more or less ugly workaround. First you rename the archetype-resources/.gitignore to __gitignore__ then inside the archetype-metadata.xml add <requiredProperties> <requiredProperty key=”gitignore”> <defaultValue>.gitignore</defaultValue> </requiredProperty> </requiredProperties> <fileSets> <fileSet> <directory></directory> <includes> <include>__gitignore__</include> … Read more

Maven 2.1.0 not passing on system properties to Java virtual machine

August 22, 2023 by Tarik

I don’t think this is a problem in either Maven or Surefire plug-in. Else the surefire is behaving differently. It looks like now, when Surefire forks the JVM, will not take all the system properties from the parent JVM. That’s why you should pass whatever system properties you want for the tests, using argLine. So, … Read more

Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its dependencies could not be resolved

August 20, 2023 by Tarik

Your debug output indicates that Clean is the first thing that it’s trying to run, so I’m guessing it’s failing to download any plugins from central. First off, see if you can download the plugin jar directly in a web browser: http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.jar If that works then your web browser has connectivity to central but maven … Read more

How to understand Maven dependency tree

August 10, 2023 by Tarik

It’s a dependency tree. The things below a listing are dependencies of their parent.

How to support multiple Scala versions in a library

August 3, 2023 by Tarik

Most of this is well supported in sbt within a single source tree Version specific source directories are usually not need. Scala programs tends to be source compatible – so often in fact that crossbuilding (http://www.scala-sbt.org/release/docs/Detailed-Topics/Cross-Build) has first class support in sbt. If you really need version specific code, you can add extra source folders. … Read more
