Compilation Participants

Identifier:

org.eclipse.jdt.core.validationParticipant

Since:

Description:

This extension point allows clients to participate in the validation process by receiving notifications at various stages of build and reconcile, via a org.eclipse.jdt.core.compiler.validationParticipant.

Configuration Markup:

definition of a compilation participant. This definition allows to order participants. Participants are run by group. The group of participants that modify the environment is run first, then the group of participants that create problems is run, finally the group of other participants is run. Inside each group, participants are ordered using their 'requires' attributes. If a 'requires' attribute point to a participant that doesn't belong to the group, it is ignored.

class - the class that implements this compilation participant. This class must implement a public subclass of org.eclipse.jdt.core.compiler.validationParticipant with a public 0-argument constructor.
id - a unique identifier for this participant
modifiesEnvironment - optionally specify whether this compilation participant modifies the environment, thus affecting binding resolution. If not specified, false is assumed.
createsProblems - optionally specifies whether this compilation participant creates problems. If not specified, false is assumed.
requiredSourceLevel - the required source level this participant needs (one of the JavaCore.VERSION* constants). If a project's source level is below this required source level, the participant will not be invoked. If this attribute is not specified, the participant will be invoked for any source level.

<!ELEMENT requires EMPTY>

<!ATTLIST requires

id CDATA #REQUIRED>

a participant that is required to run this compilation participant

id - the unique identifier of the participant that is required

<!ELEMENT managedMarker EMPTY>

<!ATTLIST managedMarker

markerType CDATA #REQUIRED>

a managed marker is created from the recorded problems (see BuildContext#recordNewProblems(CategorizedProblem[])) and is removed when the corresponding source file is re-built or when the project is cleaned

markerType - the type of the managed marker

Example of a declaration of a validationParticipant:

         class="org.eclipse.jdt.apt.core.internal.AptvalidationParticipant"
         id="APT"
         requiredSourceLevel="1.5">
      <managedMarker markerType="org.eclipse.jdt.apt.core.compile.problem"/>
