Hi,

I am having peculiar issue with Sapphire generating my model classes, i have enable the annotation processing for my Project and when I build the project i don't see any classes generated from my model , not sure what is the cause because there is no error trace too.

I putting down the snippet of my MANIFEST.MF

....
 org.eclipse.core.commands;visibility:=reexport,
 org.eclipse.emf.codegen;bundle-version="2.5.0",
 org.eclipse.emf.ecore;bundle-version="2.5.0",
 org.eclipse.jdt.core,
 org.eclipse.jem.util;bundle-version="2.0.201",
 org.eclipse.jem.workbench;bundle-version="2.0.201",
 org.eclipse.jface.text,
 org.eclipse.jst.j2ee;bundle-version="[1.1.301,2.0.0)",
 org.eclipse.jst.j2ee.core;bundle-version="[1.1.301,2.0.0)";visibility:=reexport,
 org.eclipse.jst.j2ee.web;bundle-version="[1.1.301,2.0.0)";visibility:=reexport,
 org.eclipse.wst.common.frameworks;bundle-version="[1.1.300,2.0.0)",
 org.eclipse.wst.common.project.facet.core;bundle-version="[1.4.1,2.0.0)",
 org.eclipse.wst.server.core;bundle-version="[1.1.102,2.0.0)",
 org.eclipse.wst.sse.core;bundle-version="[1.1.402,2.0.0)";visibility:=reexport,
 org.eclipse.wst.xml.core;bundle-version="[1.1.402,2.0.0)";visibility:=reexport,
 org.apache.commons.logging,
 org.eclipse.wst.validation;bundle-version="[1.2.104,1.3.0)",
 org.eclipse.sapphire.java;bundle-version="0.3.1",
 org.eclipse.sapphire.java.jdt;bundle-version="0.3.1",
 org.eclipse.sapphire.modeling;bundle-version="0.3.1",
 org.eclipse.sapphire.modeling.xml;bundle-version="0.3.1",
 org.eclipse.sapphire.osgi;bundle-version="0.3.1",
 org.eclipse.sapphire.platform;bundle-version="0.3.1",
 org.eclipse.sapphire.workspace;bundle-version="0.3.1"
....

Not sure if some other plugin is causing/preventing the code generation of Sapphire.

It works if I have only the sapphire model classes in a separate plugin.

Is there anyway to over come the issue, something like using Tycho/Ant to generate the classes at run-time/compile-time ?

I followed the http://wiki.eclipse.org/Sapphire_Modeling_Tycho_build_support on using Tycho with my Plugin build, but when I try to integrate the the customCallbacks.xml to my maven build I get the following error ,

Quote:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (generate-sources) on project ${PLUGIN_NAME}: An Ant BuildException has occured: The following error occurred while executing this line:
[ERROR]${PLUGIN_SRC_FOLDER}\build-sapphire.xml:41: The following error occurred while executing this line:
[ERROR] ${PLUGIN_SRC_FOLDER}\build-sapphire.xml:65: The

For brevity i have used


  • $PLUGIN_SRC_FOLDER- this corresponds to the Eclipse Plugin source folder in
  • $M2_REPO corresponds to the Local maven repository workspace
  • build-sapphire.xml --> customCallbacks.xml


My platform is on Windows 7 with Maven 3.0.3 and Eclipse Indigo, also I have turned off Annotation processing at the project settings to make the build free of any user specific settings.

I personally feel there is some interference with EMF and Sapphire and not sure they could be used in same project as dependencies and doubt the cause of my previous thread message could be this too ....

I was able to solve this issue ! I guess there is some issue with the Eclipse Annotation Processing (thinking ?????)

I tried to fork the Ant build with maven as mentioned above and that also failed due to some wired errors with respect to the Annotation processing, so thought to resort pure Maven way using the Maven Apt Plugin

My configuration is as follows,
<plugin>
	<groupId>org.codehaus.mojo</groupId>
	<artifactId>apt-maven-plugin</artifactId>
	<version>1.0-alpha-4</version>
	<inherited>true</inherited>
	<configuration>
		<fork>true</fork>
		<encoding>UTF-8</encoding>
		<factory>org.eclipse.sapphire.sdk.build.processor.internal.APFactory</factory>
		<sourceOutputDirectory>.apt_generated</sourceOutputDirectory>
		<outputDirectory>.apt_generated</outputDirectory>
		<meminitial>256m</meminitial>
		<maxmem>512m</maxmem>
	<!-- used for staleness checking -->
		<outputFileEndings>
			<outputFileEnding>.xml</outputFileEnding>
		</outputFileEndings>
	<!-- force skips stale checking and always generate -->
	<!-- force>true</force  -->
	</configuration>					
</plugin>


Now the code is getting generated with a warning as below,

Wondering what it is missing something from Maven Plugin class path ? or anything else and its implications .....

Don't know much about using Maven, but when it comes to annotation processing in Eclipse, I have seen problems with annotation processor not being invoked on some projects when the number of projects requiring annotation processing is high. I have always been able to resolve this issue by closing the projects that I am not working on at the moment. So... keep your workspace light and you shouldn't have any issues.

I am getting a new and consistent error when using the Eclipse APT compiler or using the Ant build.xml (customCallbacks.xml), i either get

Not sure whats going wrong, is it Eclipse Annotation processor crashing it or Sapphire Annotation Processor crashing it.

The first issue is definitely a bug in Javac/APT. This crash happens before it gets to Sapphire processor. This looks similar a bug that I've seen before. Try the resolution described here...

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6670278

The second one looks like some sort of a Maven issue. There isn't anything Sapphire related there and I cannot help you with Maven.
