Re: [m2e-users] [m2eclipse-user] m2eclipse webapp deploy to tomcat silently fails to deploy anything


please use the mailing list, as the codehaus one is deprecated (I wonder why it's still working).

Failing to deploy your web app is probably caused by some misconfiguration. In order to make sure your app is properly configured, check the following (assuming your web resources are under src/main/resources) :

- have you installed the Maven integration for WTP -aka m2eclipse-wtp -? It's available under the extras update site (
-make sure your artifact packaging is set to war
- For servlet 2.5, make sure your maven-compiler-plugin sets the source and target level to 1.5 (for web 3.0 -> compiler level = 1.6, IIRC)
- right click on your project : Maven > Update Maven Configuration.

If it still doesn't work, you can check eclipse's error log for any exception.

I had a small Spring app in Eclipse that I had originally set up as a

I started to convert it to Maven.  Initially, it was still working fine,
but I later realized I still had a "WebContent" directory, so I moved
what I needed from that to src/main/webapp.

About that time I discovered that when I deployed it to the internal
Tomcat, there were no obvious startup errors, but the app at the context
root was giving me 404s.

I then tried right-clicking on my pom.xml and selecting "Run"->"Maven
Install".  This created my war file in target.  I then edited my Tomcat
server definition and added an "external web module", pointing to that
war file and giving it a slightly different context root.  I then tested
that from my browser, and it worked fine.

How do I configure my project so that just adding the project to the
server will deploy a fully functional web app?  Am I missing something
in my "maven-war-plugin" configuration?
