Provider org.eclipse.sisu.space.SisuIndexAPT6 not found error when using m2e-apt

[mcacker]

I've installed m2e-apt in Eclipse Mars, and am running into the following error:

Caused by: org.apache.maven.plugin.CompilationFailureException: Compilation failure
error: Bad service configuration file, or exception thrown while constructing Processor object:  
javax.annotation.processing.Processor: Provider org.eclipse.sisu.space.SisuIndexAPT6 not found

The error seems to occur in several different projects, regardless whether i'm directly using annotations, though perhaps dependencies are annotated, unless I explicitly disable it using

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <compilerArgument>-proc:none</compilerArgument>
            </configuration>
        </plugin>

using

        <m2e.apt.activation>maven_plugin</m2e.apt.activation> or
        <m2e.apt.activation>disabled</m2e.apt.activation>

makes no difference. Any ideas how to fix it?

thanks, Mitchell

Do you have a sample project reproducing the error?

[mcacker]

Unfortunately, the projects i'm trying to use m2e-apt with are quite extensive, so it would be hard to provide one of these as a sample. I'll see if I can cobble one together

[fbricon]

the maven_plugin mode is very experimental. What happens if you use <m2e.apt.activation>jdt_apt</m2e.apt.activation>?

[mcacker]

I still see the error with this setting. It runs my annotations, but then I get the above error.

Just to clarify, i'm seeing the error when I run a maven build from an Eclipse run configuration. I'm not sure yet that it's running yet during incremental compilation.

[fbricon]

well m2e-apt is only relevant in the context of Eclipse builds (incremental or not), not while executing Maven build commands from the Run As menu.

m2e-apt's code is now included in https://github.com/eclipse-m2e/m2e-core , please consider reporting issue to https://github.com/eclipse-m2e/m2e-core/issues if it's still relevant.
