Example 1 with ExtensionModelLoader

use of org.mule.runtime.extension.api.loader.ExtensionModelLoader in project mule by mulesoft.

the class MuleExtensionModelLoaderManager method start.

/**
 * Will look through SPI every class that implements the {@code providerClass} and if there are repeated IDs, it will
 * collect them all to throw an exception with the detailed message.
 * <p/>
 * The exception, if thrown, will have the following message:
 * <pre>
 *   There are several loaders that return the same ID when looking up providers for 'org.mule.runtime.module.artifact.ExtensionModelLoader'. Full error list:
 *   ID [some-id] is being returned by the following classes [org.foo.FooLoader, org.bar.BarLoader]
 *   ID [another-id] is being returned by the following classes [org.foo2.FooLoader2, org.bar2.BarLoader2]
 * </pre>
 *
 * @throws IllegalStateException if there are loaders with repeated IDs.
