Could someone please assist with using Maven Clean to make a Java SNAPSHOT

I am new to Java. Am currently trying to modify some library code and then use a SNAPSHOT jar of that to use in my current project. In IntelliJ IDEA CE, I used the Maven Projects Tool Window and hit the Lifecyle -> Clean command to attempt to make the Snapshot.
I saw the following output...
[INFO] Scanning for projects...

Two questions:
1) Where is that SNAPSHOT jar located?
2) How do I make a SNAPSHOT jar that includes all dependencies?
EDIT: Resolved. Please see comments.

Maven release build fails in Jenkins due to failure to build a release version of dependency

Maven release build of EAR app fails due to failure of MODULE 2 to find a release version of MODULE 1.
Maven version is 2.2.1.

Fixed build and this is how.
I first switched to maven 3.0.2 in the Jenkins config, since as alluded to by
#khmarbaise using maven 2.2.1 was the root of issue.
But then I got wsimport errors, to fix these I removed the encoding property
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
from the parent pom.
I then got a lot of encoding errors, of the type,
error: unmappable character for encoding ANSI_X3.4-1968
so to fix these I added
-Dfile.encoding=UTF8
to the the to MAVEN OPTS props in the Jenkins job config.
The encoding errors were related to the existence of lots of 'strange' chars in JavaDoc and elsewhere in app code.

Using Maven to build Storm project but cannot find the resulted java project

I got the following output after doing command "mvn eclipse:eclipse".
It showed that the build is successful but no java project was built there.
I could not figure out why.

Encoding of a Project Java + hudson

I'm have a problem with an server Hudson.
My project java, my workspace and all class have a encoding UTF-8, but when trying to generate a build happens a error with encoding.
I use Ubuntu server 11.04, and to development Ubuntu 11.10.
the error what happening is:
/home/hudson/.hudson/jobs/SCUV/workspace/scuv.persistence/src/main/java/br/com/digitaldoc/scuv/abstracts/Bean.java:[29,18] error: unmappable character for encoding ASCII
in this line have "ã"
Anyone know how to solve this problem?

mvn tomcat:run doesn't start Tomcat

I have set it up in project's pom.xml, but when I'm calling it from command line:

And that's all. Tomcat hasn't been launched but I don't see any errors here.
Does anybody knows what's happening?

As mentioned before, you should use war packaging. However, if you can't because you're using OSGI or some other reason, you can tell the Tomcat plugin to deploy anyway even if it isn't war packaging by using the ignorePackaging option:
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat6-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<ignorePackaging>true</ignorePackaging>

The clue is in the line:
[INFO] Skipping non-war project
The tomcat:run goal is intended to work with war projects, I'm guessing yours is a jar project.
You need to change the packaging of your project to war, you may also need to provide some additional configuration for the war to actually do anything.
Note: I'd recommend having a separate war project to your jar projects, then adding the jars as dependencies to the war.

if you're using Roo, and haven't yet invoked the controller command then your configuration is not yet set to generate a WAR file.
