Enable annotation processing

Hi, I’m trying to use https://github.com/immutables/immutables which is an annotation based source code generator.

In the docs (https://immutables.github.io/apt.html), it’s mentioned that the m2e-apt Eclipse plugin needs to be configured when building in Eclipse, so presumably this is why in vscode it doesn’t work?

I was previously having problems with Rocker templates, and with hindsight this might have been related.

Environment

Operating System: xubuntu yakkety
JDK version: 1.8.0_131-b11
Visual Studio Code version: 1.17.1
Java extension version: 0.12.0
Maven 3.5
Maven compiler plugin 3.6

Steps To Reproduce

https://immutables.github.io/getstarted.html

Set up a Maven project that includes the org.immutables dependency
Add a test class that uses the @Value.Immutable annotation
vs-code-java fails to generate the source code, but a mvn compile will

Current Result

No generated source code for @Value.Immutable annotated class

Expected Result

Corresponding Immutable... class source code generated

Additional Informations

I tried adding org.jboss.tools.maven.apt.core_1.3.0.201610261805 to the extension’s server/plugins folder to see if that allowed the annotation processor to be picked up, but it wasn’t effective. I also tried putting the Immutables jar in the annotationProcessorPaths element in the maven compile plugin configuration, but it still wasn’t picked up.

Is Gradle supported as well? Having the following in build.gradle, I keep getting “[Java] AutoValue_Remark cannot be resolved to a type” errors in my project.

dependencies {
    compile 'com.google.auto.value:auto-value-annotations:1.6.2'
    annotationProcessor 'com.google.auto.value:auto-value:1.6.2'
}

(Version 0.28.0)

@simon04 I found a simple workaround for using Gradle with the annotationProcessor features (Immutables, AutoValue, Metamodels).

The idea is to add manually the location of the generated sources. In my case, I just had to add build/generated/source/apt/main to srcDirs:

sourceSets {
    main {
        java {
            srcDirs = ['src/main/java', 'build/generated/source/apt/main']
        }
    }
}

I don’t know if it is a good idea or whatever, but it works and helps me get the job done 😁
