Maven: project.build.directory

This is continuation to my previous post, Super POM.

As you see the super pom file, you can see many variables like below.

<directory>${project.basedir}/target</directory>
<outputDirectory>${project.build.directory}/classes</outputDirectory>
<finalName>${project.artifactId}-${project.version}</finalName>
<testOutputDirectory>${project.build.directory}/test-classes</testOutputDirectory>
<sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
<scriptSourceDirectory>${project.basedir}/src/main/scripts</scriptSourceDirectory>
<testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>

'project.build.directory' represents the directory where all the build artifacts goes. These properties values change from project to project.

To see actual values of these properties, go to the pom file location of your project and execute the command 'mvn help:effective-pom'.

Above properties will be replaced with actual values.

<sourceDirectory>C:\Users\krishna\Documents\Study\Maven\projects\helloWorld\src\main\java</sourceDirectory>
<scriptSourceDirectory>C:\Users\krishna\Documents\Study\Maven\projects\helloWorld\src\main\scripts</scriptSourceDirectory>
<testSourceDirectory>C:\Users\krishna\Documents\Study\Maven\projects\helloWorld\src\test\java</testSourceDirectory>
<outputDirectory>C:\Users\krishna\Documents\Study\Maven\projects\helloWorld\target\classes</outputDirectory>
<testOutputDirectory>C:\Users\krishna\Documents\Study\Maven\projects\helloWorld\target\test-classes</testOutputDirectory>

Maven: Effective POM

In my previous post, I explained about super pom. By default all the pom files inherit the information from super pom file.

pom.xml

<project>
   <modelVersion>4.0.0</modelVersion>
   <groupId>selfLearningJava</groupId>
   <artifactId>helloworld</artifactId>
   <packaging>jar</packaging>
   <version>1</version>
   <name>helloworld</name>
</project>

For example, if you would like to see the final pom, after inheriting from super pom, then go to the directory, where your pom.xml file is located and run below command

mvn help:effective-pom
