Hi
I worked through the step-by-step of the JavaFX example and all was ok until step 5. This is where you go to the directory java24trainer/java-ee/lesson37 and run "mvn install" command.
I always get an error - BUILD FAILURE. I have checked the PATH settings and it looks ok, with all the necessary paths in there.

The error I get is:

[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 0.346s
[INFO] Finished at: Fri Jun 24 12:18:50 BST 2011

[INFO] ------------------------------------------------------------------------
[ERROR] Error resolving version for plugin 'com.practicaljava.maven.plugin:gf-plugin' from the repositories [local (/Users/Patrick/.m2/repository), maven.glassfish.java.net (http://download.java.net/maven/glassfish), central (http://repo1.maven.org/maven2)]: Plugin not found in any plugin repository -> [Help 1]
[ERROR]

Also there is a warning before this error is shown, which is:

[WARNING] Some problems were encountered while building the effective model for com.practicaljava:lesson37-javafx-ui:jar:1.0
[WARNING] 'build.plugins.plugin.version' for com.practicaljava.maven.plugin:jfx-plugin is missing. @ line 32, column 21

This error at step 5 also seems to mean step 8 doesn't work, so I'm stuck at this point, which is a shame, as I'd like to see JavaFX in action, having set it up myself.

Any help appreciated.

Check what version you're using Maven. Examples from the book compiled using version 2.2.1. It is quite possible that you are using version 3.0, which gives Build erros

I get the same "Error resolving version for plugin gf-plugin" when running the script to create a new domain in GlassFish (Step 8 of Try It).
I use GlassFish Server 3.1.2 Open Source Edition, Apache Maven 3.0.4, Java version 1.7.0_02.
I'm stuck and don't know what to do next, any help appreciated.
