Executing task ':generateInterfaces' results in failure

[lu4nm3]

Hello. I'm trying to use the griddle plugin to generate the default Java classes that you normally get from Thrift (ie. without Scrooge). To do this I configured my build.gradle file like so:

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }

    dependencies {
        classpath 'com.google.protobuf:protobuf-gradle-plugin:0.7.7'
        classpath 'com.yodle.griddle:griddle:1.7'
    }
}

plugins {
    id "com.commercehub.gradle.plugin.avro" version "0.8.0"
}

apply plugin: 'idl'
apply plugin: 'thrift'
apply plugin: 'scala'
apply plugin: "com.google.protobuf"
apply plugin: 'idea'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.scala-lang:scala-library:2.11.7',
            'com.google.protobuf:protobuf-java:3.0.0-beta-2',
            'com.google.protobuf:protobuf-java-util:3.0.0-beta-2',
            'org.apache.tinkerpop:tinkerpop:3.2.0-incubating',
            'org.apache.tinkerpop:gremlin-core:3.2.0-incubating',
            'com.michaelpollmeier:gremlin-scala_2.11:3.1.0-incubating.2',
            'com.trueaccord.scalapb:scalapb-runtime_2.11:0.5.26',
            'com.trueaccord.scalapb:scalapb-json4s_2.11:0.1.1',
            'org.apache.avro:avro:1.7.7'

    compile 'org.apache.thrift:libthrift:0.9.3'
}

sourceSets {
    main {
        proto {
            srcDirs = ['src/main/protobuf']
        }
        scala {
            srcDirs = ['src/main/scala', "$protobuf.generatedFilesBaseDir", "$thriftGenDir"]
        }
    }
    test {
        proto {
            srcDirs = ['src/test/protobuf']
        }
        scala {
            srcDirs = ['src/test/scala', "$protobuf.generatedFilesBaseDir", "$thriftGenDir"]
        }
    }
}

idea {
    module {
        sourceDirs += file("$protobuf.generatedFilesBaseDir");
    }
}

protobuf {
    // Configure the protoc executable
    protoc {
        // Download from repositories
        artifact = 'com.google.protobuf:protoc:3.0.0-beta-2'
    }
    //    generatedFilesBaseDir = "$buildDir/generated-sources/main"
}

avro {
    createSetters = false
    fieldVisibility = "PRIVATE"
}

/**
 * Task will use the ScalaPB binary to generate Scala classes using the .proto IDL files
 * */
task generateScalaPB(type: Exec) {
    workingDir 'src/main/protobuf'
    commandLine './scalapbc-0.5.26/bin/scalapbc'
    def protoFiles = fileTree(dir: "src/main/protobuf", include: '**/*.proto').
            getFiles().
            collect() { file -> file.name }
    args = [protoFiles, "--scala_out=flat_package:$protobuf.generatedFilesBaseDir"].flatten()
}

compileScala {
    dependsOn generateScalaPB
}

thriftSrcDir = "${projectDir}/src/main/idl"

Excuse the length build.gradle file. I'm in the process of testing out Protobuf and Avro in addition to Thrift but I thought I would provide the entire file in case there is a known compatibility issue in any of that.

Anyways, when I go to run the generateInterfaces task for gradle, I get the following output: Note: That I'm running Gradle 2.13 on IntelliJ but the command above I ran from the terminal.

bash$ ./gradlew generateInterfaces --info

Any idea what might be going on when it says that the "generateInterfaces" task changed type?

[dkesler]

Did you try the scrooge plugin at first? it looks like gradle is saying the reason it's running generateInterfaces is because the task type changed. I think your issue is unrelated.

Can you paste a copy of your test.idl file?

[dkesler]

Actually, instead of just your test.idl file, would it be possible for you to tar up your entire project as is?

Also, two other things that may be useful to try:

1. Try running with --stacktrace to see if that gives you more info on why the thrift command failed.
2. Try manually running the thrift command gradle is trying to run to see if that gives you a better error message about why the thrift command is failing.
