Missing dependencies - maven-2

Question

i get suddenly an error message, that 3 dependencies are missing: gwt-user.jar, gwt-dev.jar and gxt.jar. All jars are in my local repo:
dage [~/.m2/repository] $ ls -l com/google/gwt/gwt-user
insgesamt 12

and the pom entry is:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-servlet</artifactId>
<version>${gwt.version}</version>
<scope>runtime</scope>
</dependency>
<dependency>

<artifactId>gwt-user</artifactId>
<version>${gwt.version}</version>
<scope>system</scope>
<systemPath>${gwt.home}/gwt-user.jar</systemPath>
</dependency>
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-dev</artifactId>
<version>${gwt.version}</version>
<scope>system</scope>
<systemPath>${gwt.home}/gwt-dev.jar</systemPath>
</dependency>
<!-- Needed for ExtGWT -->
<dependency>
<groupId>com.extjs</groupId>
<artifactId>gxt</artifactId>
<version>${gxt.version}</version>
<scope>provided</scope>
</dependency>
<properties>
<gwt.version>2.0.0</gwt.version>
<gxt.version>2.1.0</gxt.version>
</properties>
I don't have made any maven changes and the pom was also not changed. I've just added and modified java/css/hml files. Any ideas, what is wrong?
edit: Exact message is
Missing:
----------
1) com.google.gwt:gwt-user:jar:2.0.0
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=com.google.gwt -DartifactId=gwt-user -Dversion=2.0.0 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=com.google.gwt -DartifactId=gwt-user -Dversion=2.0.0 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
.
.
.
and I build the project in command line.

Answer 1

I get suddenly an error message, that 3 dependencies are missing: gwt-user.jar, gwt-dev.jar and gxt.jar. All jars are in my local repo:
Where? On the command line? In your IDE? If this is happening in your IDE and if you are using Eclipse and the m2eclipse plugin, I've noticed that Eclipse sometimes gets lost after POM changes. In that case, right click on the project, then select Maven > Update Project Configuration. Works for me.

i can't explain it, but after reboot is working again...
