Problems while upgrading a GWT maven project from GWT 2.1 SNAPSHOT to GWT 2.1.0 final release

[vsdev]

I tried to upgrade a working GWT maven project from GWT 2.1 SNAPSHOT
to the GWT 2.1.0 final release. That is, I changed the GWT version in
the pom.xml from 2.1-SNAPSHOT to 2.1.0.

After doing that, I got the following error during the maven build
(mvn install):
[INFO] Unable to find resource 'com.google.gwt:gwt-soyc-vis:jar:2.1.0'
in repository central (http://central)

Then I read that upgrading the version of the gwt-maven-plugin in the
pom.xml from 1.3.1.google to 1.3.2.google should fix this problem. As
I didn't find a public maven repository containing the corresponding
artefacts I downloaded the jar manually from
http://google-web-toolkit.googlecode.com/svn/2.1.0/gwt/maven/org/codehaus/mojo/gwt-maven-plugin/1.3.2.google/
and installed it in my local maven repository. But now I get another
error
during the maven build:

[INFO] Internal error in the plugin manager executing goal
'org.codehaus.mojo:gwt-maven-plugin:1.3.2.google:compile': Unable to
load the mojo 'org.codehaus.mojo:gwt-maven-plugin:
1.3.2.google:compile' in the plugin 'org.codehaus.mojo:gwt-maven-
plugin'. A required class is missing: org/codehaus/plexus/util/xml/
XmlStreamReader org.codehaus.plexus.util.xml.XmlStreamReader

What do I wrong? Could you give me a short tutorial how to upgrade a
GWT maven project from GWT 2.1 SNAPSHOT to GWT 2.1.0 final release?

Hi vsdev,

I think you're the 3rd person to run into the plexus error on the
list. As far as I know, starting with a fresh local maven repo
resolves it.

Please post back with your progress.

Hi David

starting with a fresh local maven repository didn't resolve the bug
for me. Below I post more detailed information from the maven output -
maybe you have another idea?

Hi Volker,

See this thread for more info:
https://mail.google.com/mail/?shva=1#apps/plexus/12be70cd49b26076

The only difference I can see is that you installed
gwt-maven-plugin:1.3.2.google manually, whereas Hilco in the other
thread added a repo in the POM as in the Expenses sample POM.

As noted in other threads, we're working to get
gwt-maven-plugin:1.3.2.google changes back into gwt-maven-plugin.

HTH,

Hi David,

Thanks for your answer but the link redirects to google mail;) Could
you post the correct link?

When do you plan to get the gwt-maven-plugin:1.3.2.google changes back
into the gwt-maven-plugin?

Oops, here you go:

Setting the version of the GWT maven plugin to 2.1.0 (which is
released now) in the pom.xml solved the problem.
