What is the difference between “pom” type dependency with scope “import” and without “import”?
You can only import managed dependencies. This means you can only import other POMs into the dependencyManagement section of your project’s POM. i.e. … <dependencyManagement> <dependencies> <dependency> <groupId>other.pom.group.id</groupId> <artifactId>other-pom-artifact-id</artifactId> <version>SNAPSHOT</version> <scope>import</scope> <type>pom</type> </dependency> </dependencies> </dependencyManagement> … What then happens is that all the dependencies defined in the dependencyManagement section of the other-pom-artifact-id are included in … Read more
What is the difference in Maven between dependency and plugin tags in pom.xml?

Maven: The packaging for this project did not assign a file to the build artifact

Another thing to test would be to declare the mail artifact with the version required by ALL-DEPS under the dependencyManagement … Read more

stop IntelliJ IDEA to switch java language level every time the pom is reloaded (or change the default project language level)
As per Mark’s comment, here is how to do it: <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build>
What does mvn install in maven exactly do
As you might be aware of, Maven is a build automation tool provided by Apache which does more than dependency management. We can make it as a peer of Ant and Makefile which downloads all of the dependencies required. On a mvn install, it frames a dependency tree based on the project configuration pom.xml on … Read more
How to refer environment variable in POM.xml?
