Just to confirm, my team has also run into this issue just recently today (11/24).
This will definitely impact a large number of people. I found the old issue from April talking about the codehaus plugin, and whether or not this project (google gwt-maven) was going to change their prefix or not. For those still stuck, resolution is to instead of 'mvn gwt:gwt', use: mvn com.totsp.gwt:maven-googlewebtoolkit2-plugin:gwt Reference link: http://code.google.com/p/gwt-maven/issues/detail?id=107 -D --- On Mon, 11/24/08, Mirko Nasato <[EMAIL PROTECTED]> wrote: From: Mirko Nasato <[EMAIL PROTECTED]> Subject: Re: uses codehaus mojo plugin instead of gwt-maven To: [email protected] Date: Monday, November 24, 2008, 12:58 PM Hi Arthur, Well it does say here that org.codehaus.mojo will be searched by default http://maven.apache.org/guides/introduction/introduction-to-plugin-prefix-mapping.html and it does seem that the other gwt-maven-plugin has been uploaded to the central maven repository a couple of days ago http://repo1.maven.org/maven2/org/codehaus/mojo/gwt-maven-plugin/1.0/ so what you say makes sense. But if I type mvn gwt:gwt inside a project that doesn't declare any gwt-maven plugin, what I get is [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'gwt'. [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] The plugin 'org.apache.maven.plugins:maven-gwt-plugin' does not exist or no valid version could be found and everything is working fine for me. So at this point the weird thing is: why is it still working for me? Are other people having problems?
