# Java Runtime Classpath Entry Resolvers

###### Identifier:

org.eclipse.jdt.launching.runtimeClasspathEntryResolvers

###### Description:

This extension point allows clients to dynamically resolve entries used on the runtime classpath and source lookup path, for corresponding classpath variables and classpath containers.

###### Configuration Markup:

- point - a fully qualified identifier of the target extension point
- id - an optional identifier of the extension instance
- name - an optional name of the extension instance

- id - a unique identifier that can be used to reference this resolver.
- class - the class that implements this resolver. The class must implement `IRuntimeClasspathEntryResolver`.
- variable - the name of the classpath variable this resolver is registered for. At least one of variable or container must be specified, and at most one resolver can be registered for a variable or container.
- container - the identifier of the classpath container this resolver is registered for. At least one of variable or container must be specified, and at most one resolver can be registered for a variable or container.
- runtimeClasspathEntryId - the identifier of the runtime classpath entry this resolver is associated with

###### Examples:

The following is an example of a resolver:

     <extension point="org.eclipse.jdt.launching.runtimeClasspathEntryResolvers">
      <runtimeClasspathEntryResolver
       class="com.example.ResolverImplementation"
       id="com.example.ResolverId"
       variable="CLASSPATH_VARIABLE">
      </runtimeClasspathEntryResolver>
     </extension>

###### Supplied Implementation:

Implementations are provided for the standard JRE_LIB classpath variable and JRE_CONTAINER classpath container.
