getting “Class not found: org.eclipse.ajdt.core.ant.AJDT_AjcCompilerAdapter” in eclipse 3.8

Question

i have been successfully using ajdt in conjunction with pde headless build in eclipse 3.6. i have the following entries in project's build.properties:

compilerAdapter=org.eclipse.ajdt.core.ant.AJDT_AjcCompilerAdapter
sourceFileExtensions=*.java, *.aj

however, once i switched to eclipse 3.8, i have been getting the following stack during my ant-based pde headless build:

[java] c:\eclipse3.8\plugins\org.eclipse.pde.build_3.8.0.v20120523-1555\scripts\productBuild\productBuild.xml:43: The following error occurred while executing this line:

Answer 1

It is possible that AJDT is not installed in your build eclipse. It needs to be around in order for the AJDT_AjcCompilerAdapter class to be found.
