I am trying to run a simple Java project. I had created a project using the 'Maven Project' type. I have one main class called 'TestMain'. When I tried to run the project using right click -> run, there was no menu to run the application as 'Run As Java Application'. I am wondering where that option has gone.
Can anyone please help me to run the Java application?
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.
(Alt + Shift + X) , then M to Run Maven Build. You will need to specify the Maven goals you want on Run -> Run Configurations
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.
