change default port 8080 maven gae goal appengine:devserver

Question

I'm having a problem, probably is quite simple but I did not find the solution yet.

I'm trying to launch my local GAE server (through Run-configurations of Eclipse) on a specific port (8888 in my case) but it starts only at default port 8080 and after trying with different options ... I'm not lucky

Any ideas?

Answer 1

Run this from the cmd line: mvn help:describe -Dcmd=appengine:devserver -Ddetail - you'll see all the available options for appengine:devserver goal.

The one that you want is:

mvn appengine:devserver -Dappengine.port=8888

Answer 2

The Google Plugin for eclipse (GPE) allows you to specify the port number on the second tab ('Server') in a run configuration.

If you're not using that (which you probably should be) you can configure the port in your pom directly like this:

<plugin>
    <groupId>com.google.appengine</groupId>
    <artifactId>appengine-maven-plugin</artifactId>
    <version>${gae.version}</version>
    <configuration>
        <port>8080</port>
        <address>0.0.0.0</address>
    </configuration>
</plugin>
