Getting error "org.apache.flex.compiler:mxmlc:jar" when trying to compile with FlexMojos 7.0.1 and Apache Flex 4.14 - apache-flex

Question

I'm migrating an application I had working with Adobe Flex 4.6 and FlexMojos 4 to Apache Flex 4.14 and FlexMojos 7. When I try to execute "mvn build" I'm getting this error:
[ERROR] Unresolveable build extension: Plugin net.flexmojos.oss:flexmojos-maven-plugin:7.0.1 or one of its dependencies could not be resolved:

I'm using Maven 3.2.5 and Java 1.6.0_14:
Apache Maven 3.2.5 (12a6b3acb947671f09b81f49094c53f426d8cea1; 2014-12-14T12:29:23-05:00)
Maven home: /usr/local/maven
Java version: 1.6.0_14, vendor: Sun Microsystems Inc.
Java home: /usr/java/jdk1.6.0_14/jre
Default locale: en_US, platform encoding: ANSI_X3.4-1968
OS name: "linux", version: "2.6.21.7-2.fc8xen", arch: "i386", family: "unix"
These are the steps I have followed:
I downloaded the Apache Flex SDK with the Installer:
Apache Flex SDK 4.14.1
AIR 18.0
Flash Player 18
I have used the Mavenizer to create a Maven version of this SDK:
Then I have deployed the mavenized version in my /root/.m2/repository/ folder and executed mvn compile with the pom.xml.

Answer 1

By the way in the meanwhile the mavenizer has evolved quite a bit ... making usage of maven extensions by ".mvn/extensions.xml" files. This should automatically download, convert and install the Flex/Flash/Air resources you reference. So to upgrade to the next Flex/Flash/Air version, just reference a new version and the plugin will take care of the rest (As long as the version actually exists). See more details here: https://cwiki.apache.org/confluence/display/FLEX/Preparing+FDKs+for+Maven+builds (Pay some special attention to the chapter: Prepare the FDK resources using the flex-sdk-converter-maven-extension)
