Post subject: Invoke goals on resource changes  PostPosted: Jun 16, 2011 - 02:27 PM

I have a web application which is basically an empty container runtime. and the application is made up from plugins (jar files).

a jar file/plugin. contains java classes, web resources (facelet fragments) and config files (faces and spring).

the plugin container monitors a hot deploy folder, because every plugin has its own seperate spring context and runs in isolatiomn, plugins can be replaced at runtime, a server or application restart is not necesary.

i attached an ant-task to the install phase:


                        <copy todir="${plugin.deploy.location}"

now, eveytime a developer changes a plugin, he/she needs to run install and the plugin gets deployed to the watch folder. But this is a slight pain in the rear because its repetitive work so i am on a mission to automate this process.

I figured two solutions for this.

invoke "install" on resource changes:
this is a project setting under Lifecycle mapping. it executes "install" everytime you safe a resource ( i actually configured the src/main/java folder to be a resource folder too, excluding all **/*.java files so that it also executes "install" when a java file is saved). So far so good, the trigger mechanism works fine, but the execution fails:

16/06/11 13:46:45 BST: Build errors for WebMenuPlugin; org.apache.maven.plugin.PluginResolutionException: Plugin org.apache.maven.plugins:maven-install-plugin:2.3 or one of its dependencies could not be resolved: The repository system is offline and the requested artifact is not locally available at C:\Users\XXXXXX\.m2\repository\org\apache\maven\plugins\maven-install-plugin] -->.3\maven-install-plugin-2.3.jar

from the specified remote repositories:
  archiva.park.web (http://XXXX:8080/archiva/repository/parkweb, releases=true, snapshots=false)

why is it saying the repository system is offline? is there a "offline" switch somewhere?

solution B, adding a maven builder:
I added a maven builder to my project, set "Auto Build Goals" to "install". But when the builder is active and i save a resource, it either tells me that "install" is not a valid phase, but also lists install as a valid phase...?!?! or, it shows

16/06/11 14:19:36 BST: Build errors for WebMenuPlugin; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.4.1:resources (default-resources) on project web-menu-plugin: Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.4.1:resources failed: Unable to load the mojo 'resources' in the plugin 'org.apache.maven.plugins:maven-resources-plugin:2.4.1'. A required class is missing: org/apache/maven/shared/filtering/MavenFilteringException

has anyone an idea why this would fail? or maybe a there is a better way to do this auto-deploy/install thing?
we use apache archiva internally, but the errors are the same if i use the maven repository directly.

any Maven Builder i set up compains that there is no goal to run.

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>.
