Using with other annotation processor

[larten]

Hello,

butterknife is a default library to development, so I must use it!

But I would like to use json parser.

And this part of gradle block butterknife:

compileJava {
  doFirst {
    // Directory should exists before compilation started.
    generatedSourcesDir.mkdirs()
  }
  options.compilerArgs += [
                       '-processor',
                       'com.instagram.common.json.annotation.processor.JsonAnnotationProcessor',
                       '-s',
                       generatedSourcesDir
  ]
}

What is the proper way to use both libraries together? Others recommended to use ig-json-parser with android-apt but I don't know how can I.

bg,
Larten

What happens when you combine the two?

[larten]

Butterknife doesn't working.

I'm using both together without a problem. I don't believe I had to make any changes either. Have you confirmed that IG JSON Parser is working properly on its own?

[larten]

My json models are in the android app module and if gradle task for ig-json-parser is uncommented, than it's generate correctly the models and I get NullPointerException for every view, but if I comment this, than work.

[TommyVisic]

I think you need to put IG parser in its own module. Now that I think about it, I did run into an issue w/ the java gradle plugin causing some kind of incompatibility when merge with the main build.gradle. I know the IG folks use the parser in this way too as not to expose the models' members with default visibility. Here's how we have it set up.

[larten]

Okay, maybe it will be good, but now my classes don't see generated files in model modul.
Could you share this part of your gradle script?

settings.gradle

include ':tastemade'
include ':tastemade:jsonModels'

app module build.gradle

apply plugin: 'android'

android {
    ...
}

dependencies {
    compile 'com.jakewharton:butterknife:5.1.2'
    compile project(':tastemade:jsonModels')
    ...
}

jsonModels module build.gradle

apply plugin: 'java'

ext {
    generatedSourcesDir = file("gen-src/main/java")
}

sourceSets {
    main {
        java {
            srcDir 'src/main/java'
        }
    }
    gensrc {
        java {
            srcDir 'gen-src/main/java'
        }
    }
}

compileJava {
    doFirst {
        // Directory should exists before compilation started.
        generatedSourcesDir.mkdirs()
    }
    options.compilerArgs += [
            '-processor',
            'com.instagram.common.json.annotation.processor.JsonAnnotationProcessor',
            '-s',
            generatedSourcesDir

    ]

    sourceCompatibility = JavaVersion.VERSION_1_7
    targetCompatibility = JavaVersion.VERSION_1_7
}

dependencies {
    compile 'com.instagram:ig-json-parser-processor:0.0.3'
}

Hello,
I have the same problem.
I did everything you wrote, but my app modul can't see the properly generated helper methods, just the models I wrote.
Do you have any advice?

thx,
Szöszi

[larten]

I have same problem :(

[ttung]

Sorry for the late response. Generally, we do indeed put the models in separate modules to avoid inadvertent access to package-privacy fields. However, there should be nothing that requires that behavior.

Unsure what's going on with the interaction with Butterknife, I will try it out when I get a chance.

In the meanwhile, I pushed a change so that the jar file tells the compiler how to invoke the annotation processor. Maybe that will help the issue? LMK!
