I've been developing in Java using maven for a few days now. Today I edited my pom.xml based on these instructions. Suddenly running mvn compile is giving me errors as if I was compiling with an older version of java. Stuff like:
error: generics are not supported in -source 1.3
Now I've paired my pom.xml back to its original content, and I'm still getting this error. I've done a mvn clean and deleted everything under target, and am still having this problem.
Here's a snippet of maven running the compilation phase:

This had been working fine up until today. I'm not sure what setting I might have changed or how I could have munged up my project. I even double checked that the correct versions of java are installed:
doug#doug-VirtualBox:~/lucid/bah-bio-demo/bahToBeh$ java -version
java version "1.7.0_10"
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)
doug#doug-VirtualBox:~/lucid/bah-bio-demo/bahToBeh$ javac -version
javac 1.7.0_10
Here is JAVA_HOME
doug#doug-VirtualBox:~/lucid/bah-bio-demo/bahToBeh$ echo $JAVA_HOME
/usr/lib/jvm/java-7-oracle
Maven IS using the pom.xml I think it is, if I run mvn -X compile I get:
DEBUG] (f) project = MavenProject: com.lucid:bahToBeh:1.0-SNAPSHOT # /home/doug/lucid/bah-bio-demo/bahToBeh/pom.xml
I've also deleted my maven repo rm -rf ~/.m2 and saw maven redownload everything same problem.
EDIT -- It suddenly works mysteriously
I have no idea what happened, but suddenly now its working. I thought that one thing I changed was I commented out a test. I went and uncommented out the test and then ran mvn compile and this time it compiled. Some state somewhere was out-of-sync and now things magically work?
I hate not knowing why my tools suddenly go wonky, so this is not an answer to the question, merely more information.
EDIT -- and it also just suddenly STOPPED working again
Looks like fully specifying the version to compile works though, so dingding thats the winner.
Set the source and target java versions explicitly. http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html

As a workaround you can try this (given that it is very specific to an environment, this could help).
You can enforce the version of compilation using the plugin.
Maven compilation plugin.
Good luck!

How to deal with it ?
The issue is that the maven compiler plugin is configured by default to use the a Java 1.5 compiler (see the source and target options in the official documentation) while Bitnami Tomcat Stack is includes Java 1.7. You will need to configure your projects to use Java 1.7 instead. For this you can define a different value for the maven.compiler.source and maven.compiler.target properties or define the maven.compiler.compilerVersion instead which will work as well. In both cases you need to set maven.compiler.fork to true. The example below shows how to configure this per project:
pom.xml:
<project>
(...)
<properties>
<maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>
<maven.compiler.fork>true</maven.compiler.fork>
</properties>
(...)
</project>
However you will likely want to define these settings as global settings for all your projects. In that case you can edit the settings.xml in ($M2_HOME/conf/settings.xml) and define a profile which will be always actived:
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" ...>
(...)
<profiles>
<profile>
<id>env-dev</id>
<properties>
<maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>
<maven.compiler.fork>true</maven.compiler.fork>
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>env-dev</activeProfile>
</activeProfiles>
</settings>
kaysa's answer is correct. The solution, however, can be achieved a little easier by adding a maven-compiler-plugin to your pom as shown below:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.0</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</build>
I'm not sure if this helps you or not. add a profile to your pom.xml :)
<profiles>
<profile>
<id>default-tools.jar</id>
<activation>
<property>
<name>java.vendor</name>
<value>Oracle Corporation</value>
</property>
</activation>
<dependencies>
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.4.2</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>
</dependencies>
</profile>
</profiles>
give your true tools.jar address and run maven with this profile
if it's not working forget that and change your java home to something like : /opt/bitnami/jdk1.7.0_51/jre:)

How to fix it?
Your issue is most likely the <scope> of the dependency. When inside of the IDE, all scopes are added to the build path of the project. However, when running mvn only the appropriate scopes are added to the classpath for the javac command. For example, if you had a class in /src/main/java that imported a class from one of your dependencies scoped to <scope>test</scope>, the IDE would be able to build the project, but mvn would fail in the manner you are experiencing.

It turns out that while I had updated my version of Java from 1.6 to 1.7, I had not updated Javac from 1.6 to 1.7.
To do so I used the following command on ubuntu
sudo update-alternatives --config javac
And then choose the desired version at the prompt.
There are 2 choices for the alternative javac (providing /usr/bin/javac).
Selection Path Priority Status

I hope this helps someone else.

How do I solve it? i am using MS Windows xp and Maven 2.0.11
[update based on #Raymond hint to look into README.txt at old repository location]
The repository has moved so you must change the repository URL. Change all the repository urls from
http://qtjambi.sourceforge.net/maven2/
to
http://repository.qt-jambi.org/nexus/content/repositories/releases-before-2011/
Also check the new home page at http://qt-jambi.org for additional info. At this new repository 4.6.3_04 is available for the maven plugin. 4.5.2_01, 4.6.2 and 4.6.3 are available qtjambi itself.
If you browse to the README you'll find a link at the bottom to the repository. Update your pom.xml then rerun maven:
$ mvn --update-plugins clean install
$ mvn --version
Apache Maven 3.0.4 (r1232337; 2012-01-17 00:44:56-0800)
Maven home: /home/user/apache-maven-3.0.4
Java version: 1.7.0_09, vendor: Oracle Corporation
Java home: /home/user/jdk1.7.0_09/jre
Default locale: en_CA, platform encoding: UTF-8
OS name: "linux", version: "3.5.0-18-generic", arch: "amd64", family: "unix"
Try adding the version to the plugin it may not be being resolved automatically:
<version>4.6.3_04</version>
The available versions you can use for the plugin is at the repository url:
http://old.qt-jambi.org/maven2/net/sf/qtjambi/qtjambi-maven-plugin/
At a guess you'd probably need the same plugin version as the version of qtjambi so in this case you'd need to find the appropriate repository.

Has anyone encountered this issue? I don't understand how it works on my OS X computer but not on Linux (which I don't think is the issue).
Thank you for taking the time to read this.
I would completely remove the entire repositories element in your pom.xml file. This way maven will use the standard central repository. Then change the version of jersey-server to 1.15 (the latest).
The latest jersey in that java.net repository is dated august 2011, while the standard central maven repository has version 1.15 dated October 30 2012.
I suspect that the reason it works on one machine and not the other is that in your ~/.m2/repository cache you have good cached files on one machine but not on the other. It may be necessary to delete the entire ~/.m2/repository/com/sun/jersey hierarchy and rebuild. You may have corrupted files there.
