Maven Plugin - mvn release:prepare - maven-2

Hi i'm checking via new created plugin (mpc) some parts of the pom (scm area)...but now i faced that during the mvn release:prepare of a different modules which uses the created plugin (mpc) I got the following messages:
[INFO] [INFO] Scanning the projects...
[INFO] [INFO] ...
[INFO] [INFO] not a working copy....
The output "not a working copy" ...is because I'm checking the svn info output...
The question is can I recogdnize this state during the mvn release:prepare somehow ? for example via roperties or checking an attribute of the current project ? Which means in other words that I know inside my maven plugin (mpc) that currently the release:prepare cycle is running?

I found a solution. I simply check if the current build is building an SNAPSHOT version or not (ArtifactUtil.isSnapshot() very helpfull).

Maven child modules not being built

I have a relativey simple multi module maven buid with a parent pom. This includes the 2 child modules as follows:
<modules>
<module>WebApp</module>
<module>WebService</module>
</modules>
When I run mvn clean install on the top level pom it cleans & installs each child module as expected. However I am now trying to add a plugin (codehaus weblogic) goal to deploy the WebApp .war to Weblogic 10.3.4 e.g. mvn clean install weblogic:deploy. For some reason this does not run the clean and install phases but does the deploy. If I run the command from within the WebApp directory it does do the clean and install before doing the deploy.
Is there some gotcha I'm missing that will not run the child life cycle phases if running a goal at the top level. Here's the command line output:

The file, 'C:\Development\Destin8SupportClient/WebApp/target/WebApp.war', does not exist.
It is running the weblogic:deploy goal on the top-level (pom!) module. This goal can only be run on a war or ear module.
You need to bind that goal in the WebApp sub-module to run in the install phase.
It is currently running on the top-level (pom!) module.
e.g. try adding the following to your weblogic configuration in the Webapp sub-module.
<executions>
<execution>
<phase>install</phase>
<goals>
<goal>deploy</goal>
</goals>
</execution>
</executions>
See also Example C-1 in this documentation
If you wish to have this run at the end of your build, once all other modules have been built, you will need to either:
re-order your sub-modules, so WebApp is last, then do as above
or, add another sub-module that will execute last, which depends on your WebApp submodule. Then, tell the weblogic plugin to use that .war file by specifying the following property maven.weblogic.war . You may want to use the dependency:copy goal first, to get the into the target dir of that last sub-module.
If you want to run the install phase first for all projects and after that deploy your projects to your webserver, you have to split the maven calls.
mvn clean install
mvn weblogic:deploy
By default, maven execute all tasks per project and to separate maven tasks the only solution to run them separately.
maven runs all the specified goals first on the parent project and then on the chldren.
From the logs it is evident that maven ran the clean and install goals of the parent and then tried to run the weblogic:deploy goal. Now, weblogic:deploy evidently is not a goal which is relevant to the parent, since it is meant to deploy a child webapp. maven does not know that and thus the failure.
Perhaps you should reconsider npellow's solution since it should work for your requirement.

Wrong working directory used when tagging Maven release

When I run release:prepare on my Maven project, it fails when attempting the scm-tag phase.
My Maven project uses Bazaar for its SCM. My plugin versions are maven-release-plugin 2.0 and maven-scm-plugin 1.4
[INFO] EXECUTING: cmd.exe /X /C "bzr tag myproj-pathway-0.0.2"
[ERROR] Not a branch: "D:/proj/".
The problem of course, is that the actual working directory/branch is D:/proj/branch; the parent is just a normal directory.
I assume the problem is with tagging since the modified POM is successfully checked in. How do I configure things so that tagging actually works correctly?

Maven grails plugin issue

I'm trying to create the pom for an existing grails project via:
mvn grails:create-pom -DgroupId=ourcompany.com
Now, we have our maven repository available in a local nexus repo:
http://ourcompany.com/nexus
But when i run the above, i get the below error
Downloading: http://ourcompany.com/nexus/content/groups/public/ourcompany/com/hibernate-core/3.3.1.GA/hibernate-core-3.3.1.GA.jar
[INFO] Unable to find resource 'ourcompany.com:hibernate-core:jar:3.3.1.GA' in repository
central (http://repo1.maven.org/maven2)
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
But it is in there at simply:
http://ourcompany.com/nexus/content/groups/public/hibernate-core/3.3.1.GA/hibernate-core-3.3.1.GA.jar
Ie, w/o the "ourcompany.com" path. From my perspective, it should just try to pull down hibernate w/o inserting the groupId, but maybe i'm not understanding how i'm supposed to run this command?
What happens is you just run:
mvn grails:create-pom

Maven jetty download dependencies

Why does every time I do "mvn jetty:run", maven tries to download some dependencies (apache poi and ojdbc jars) ? How can I disable this?

As explained in the chapter 3.5.5. Maven's Dependency Management:
A dependency in Maven isn’t just a JAR file; it’s a POM file that, in turn, may declare dependencies on other artifacts. These dependencies of dependencies are called transitive dependencies, and they are made possible by the fact that the Maven repository stores more than just bytecode; it stores metadata about artifacts.
So, when Maven downloads a JAR dependency, it doesn't only download a JAR but also the POM file. Here, Maven tries to download them, but they don't exist (only the jar files exist). So maven won't write them into the local repository and tries again next time.
There are 4 options here:
Use good citizen artifacts with POM files (or ask the responsible to fix the problem).
Use a repository manager and create and upload the POM files.
Create the POM files in your local repository (for example using install:install-file).
Live with it (sigh) and run mvn offline with the -o option to make it less painful.
why would you want to stop it? you can run it without downloading dependencies? if you still want to do so chk this out
http://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html
Look at the exlude tags
Basically, the dependencies will be downloaded the first time when you run the command, but some dependencies may need to compare its versions and try to get most up-to-date ones for you in your next time run.
If you does not always have an internet connection or just want to short your build time, you can append -o parameter which means offline to run, for example mvn jetty:run -o
Example of answer by Pascal Thivent
Create the POM files in your local repository (for example using install:install-file)
mvn install:install-file -DgroupId=org.apache.commons -DartifactId=codec -Dversion=1.3 -Dpackaging=jar -Dfile=lib/commons-codec-1.3.jar -DgeneratePom=true
mvn install:install-file -DgroupId=org.apache.commons -DartifactId=httpclient -Dversion=3.1 -Dpackaging=jar -Dfile=lib/commons-httpclient-3.1.jar -DgeneratePom=true
mvn install:install-file -DgroupId=org.apache.commons -DartifactId=logging -Dversion=1.1 -Dpackaging=jar -Dfile=lib/commons-logging-1.1.jar -DgeneratePom=true

How do I stop Maven 2.x from trying to retrieve non-existent pom.xml files for dependencies every build?

In my project, there are a number of dependencies that are transitively included from other dependencies that do not have pom.xml files available in any of our corporate repositories. These are internal jar-only libraries supported by various teams which have been uploaded into repositories for convenience from non-Maven teams, however these repositories are unfortunately not mine to play with.
For these dependencies, Maven insists on trying to retrieve the poms from each of my repository list every time I run a build, or mvn dependency:list. This means maven tries to retrieve 8x pom files from 7 different repository locations, and given this is over the global corporate WAN; it's really slow.
e.g. for one particular dependency
C:\Working\dev\workspace\project>mvn dependency:list

On the other hand, for POMs which are just invalid (older modelVersion, or corrupt/invalid XML, for example) it just checks my local repo, complains it's invalid and then continues. Which is fine; at least that doesn't try again over the WAN.
Is there a way (setting, override, repository config change) I can prevent Maven's dependency plugin/artifact resolver from repeatedly trying to locate missing POMs, if it already has the jar file in the local repo?
Specs:
Maven 2.2.1 (default superPOM plugin definitions)
JDK 1.6.0_18
Pascal's answer is correct for two local build workarounds. However, your best option is to request the owners of these projects to create POMs for the artifacts. They don't need to be complex, the simple alternative that Maven is using internally will work:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>aGroupId</groupId>
<artifactId>aArtifactId</artifactId>
<version>4.0.14i</version>
</project>
Downloading a POM is really a central concept in Maven to support transitive dependencies (actually, a dependency isn't just a JAR, see 3.5.5. Maven's Dependency Management for nice details on that) so I don't know if you can prevent it.
Of course, the right thing to do would be to fix the root cause of the problem. But if you can't, maybe you can run your build in offline mode (using the -o option). Or maybe you could just "install" the artifacts in your local repository using install:install-file and instruct the plugin to generate a pom for them using the generatePom optional parameter (but this obviously doesn't "scale" really well).
Set up a Nexus Repository (or similar) and upload the artifacts there. Nexus will automatically create basic poms for artifacts you upload.
download to local repo
setup nexus and upload
work offline
maybe the best idea is to get rid of maven all the way, it is horror !
