How to run a Maven project from Eclipse?
Well, you need to incorporate exec-maven-plugin
, this plug-in performs the same thing that you do on command prompt when you type in java -cp .;jarpaths TestMain
. You can pass argument and define which phase (test
, package
, integration
, verify
, or deploy
), you want this plug-in to call your main class.
You need to add this plug-in under <build>
tag and specify parameters. For example
<project>
...
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1.1</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>my.company.name.packageName.TestMain</mainClass>
<arguments>
<argument>myArg1</argument>
<argument>myArg2</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
...
</project>
Now, if you right-click on on the project folder and do Run As > Maven Test
, or Run As > Maven Package
or Run As > Maven Install
, the test phase
will execute and so your Main class.
Your Maven project doesn't seem to be configured as a Eclipse Java project, that is the Java nature is missing (the little 'J' in the project icon).
To enable this, the <packaging>
element in your pom.xml should be jar
(or similar).
Then, right-click the project and select Maven > Update Project Configuration
For this to work, you need to have m2eclipse installed. But since you had the _ New ... > New Maven Project_ wizard, I assume you have m2eclipse installed.
(Alt + Shift + X) , then M
to Run Maven Build. You will need to specify the Maven goals you want on Run -> Run Configurations
