addPluginsFrom(...) is not finding my plugin

[galliv...@gmail.com]

First, thank you for this library. I have it up and working (minus this issue) in under 5 minutes.

My issue is regarding loading a custom plugin. I have the following relevant classes:

IPerson (interface which extends Plugin)
Person (class which inherits IPerson and uses the @PluginImplementation annotation)
PluginLoader (class which has a static variable PluginManager and the function:

public static List<IPerson> getPeoplePlugins() {
    PluginManagerUtil util = new PluginManagerUtil(pluginManager);
    System.out.println(util.getPlugins(IPerson.class) + " -- " + util.getPlugins());
    // ...
}

Note: I've also added the plugins using pluginManager.addPluginsFrom(New File(PLUGIN_DIR).toURI());

However, what is outputted is: "5 -- 0" meaning it found 5 Plugins but 0 of the IPerson variant. The Plugins it found are:

>>> Class Report <<<

>>> Object Report <<<
    net.xeoh.plugins.base.impl.PluginInformationImpl@3a56860b (status:'ACTIVE')
    net.xeoh.plugins.base.impl.PluginManagerImpl@360dc67e (status:'ACTIVE')
    net.xeoh.plugins.base.impl.PluginConfigurationImpl@7f712b3a (status:'ACTIVE')
    net.xeoh.plugins.informationbroker.impl.InformationBrokerImpl@527736bd (status:'ACTIVE')
    net.xeoh.plugins.diagnosis.local.impl.DiagnosisImpl@67a5a19 (status:'ACTIVE')

Is there anything I am missing / something to do with my static function?

I seem to have fixed by problem by using:

addPluginsFrom(new ClassURI(Person.class).toURI());

So when I add a specific .class, I can't specify its interface?

I apologize, I meant to say *directory instead of interface.

Hi,

addPluginsFrom() needs to "see" what is to be added, and where that resides. This can either be an implementing class (in which case it implicitly is / must be on the classpath already), or a path to some JARs / classes. 

When you add an interface only, JSPF won't know anything about if and where an implementing class might be. 

Cheers,

Ralf

Thanks Ralf, that makes sense.

Hi Guys,

I have similar issue and needing a solution urgently since I am running on time. I implemented JSPF with same as above mentioned code but my plugin is not loaded. I use plugins directory wherein my plugin jars reside. My plugin interface i.e. the one that implements Plugin resides with the Main project. When I compile the project in NetBeans using maven, I dont see any errors but just the plugin is not loaded and I get a NULL reference to the following code. Please help

AppPlugin appplugin = Application.getPluginManager().getPlugin(AppPlugin.class);

I load plugins using

pluginManager = PluginManagerFactory.createPluginManager();

pluginManager.addPluginsFrom(new File("plugins/").toURI(), new OptionReportAfter());

Output is:

>>> Class Report <<<

>>> Object Report <<<

No of plugins:[net.xeoh.plugins.base.impl.PluginManagerImpl@7e8bed1c, net.xeoh.plugins.base.impl.PluginConfigurationImpl@3315a56d, net.xeoh.plugins.base.impl.PluginInformationImpl@42fbc1f7, net.xeoh.plugins.informationbroker.impl.InformationBrokerImpl@66a71273, net.xeoh.plugins.diagnosis.local.impl.DiagnosisImpl@1e7b617c]

Try to change :
pluginManager.addPluginsFrom(

new File("plugins/").toURI()

to:
 pluginManager.addPluginsFrom(ClassURI.CLASSPATH);

Worked for me, i had also the "new OptionReportAfter()" call printing "Active", but that was wrong...

Thanks..got it working after I changed the way the plugin classes are packaged
