Import swagger-codegen project into existing Andro

问题:

Im trying to integrate a "module"-project generated by swagger-codegen, into my Android project.

Haven't worked that much with gradle before and the swagger-codegen creates a quite messy build.gradle from my point of view.

I have a hard time finding documentation on how to do this. And I feel a bit lost.

I used this method described in the FAQ

mvn clean package
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
 -i http://petstore.swagger.io/v2/swagger.json \
 -l java --library=okhttp-gson \
 -o /var/tmp/java/okhttp-gson/ 

So fare I tried to copy the source from the project that was generated by swagger-codegen and merge the two gradle build files. I removed the Junit tests because I couldn't get the Junit dependency working (Implementing Swagger-codegen project - Error:(23, 17) Failed to resolve: junit:junit:4.12). But then I got stuck with some conflict between the plugins?

The 'java' plugin has been applied, but it is not compatible with the Android plugins.

Here's the build.gradle:

import static jdk.nashorn.internal.runtime.regexp.joni.ApplyCaseFold.apply

apply plugin: 'idea'
apply plugin: 'eclipse'

group = 'io.swagger'
version = '1.0.0'

buildscript {
   repositories {
       jcenter()
   }
   dependencies {
       classpath 'com.android.tools.build:gradle:2.1.2'
       // classpath 'com.android.tools.build:gradle:1.5.+'
       classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
   }
}

repositories {
   jcenter()
   maven { url 'http://repo1.maven.org/maven2' }
}


if(hasProperty('target') && target == 'android') {

   apply plugin: 'com.android.library'
   apply plugin: 'com.github.dcendents.android-maven'

   android {
       compileSdkVersion 23
       buildToolsVersion '23.0.2'
       defaultConfig {
            minSdkVersion 14
            targetSdkVersion 23
       }
        compileOptions {
           sourceCompatibility JavaVersion.VERSION_1_7
           targetCompatibility JavaVersion.VERSION_1_7
       }

       // Rename the aar correctly
       libraryVariants.all { variant ->
           variant.outputs.each { output ->
               def outputFile = output.outputFile
               if (outputFile != null &&    outputFile.name.endsWith('.aar')) {
                    def fileName = "\u0024{project.name}-  \u0024{variant.baseName}-\u0024{version}.aar"
                output.outputFile = new File(outputFile.parent, fileName)
            }
        }
    }

    dependencies {
        provided 'javax.annotation:jsr250-api:1.0'
    }
}

afterEvaluate {
    android.libraryVariants.all { variant ->
        def task = project.tasks.create "jar${variant.name.capitalize()}", Jar
        task.description = "Create jar artifact for ${variant.name}"
        task.dependsOn variant.javaCompile
        task.from variant.javaCompile.destinationDir
        task.destinationDir = project.file("${project.buildDir}/outputs/jar")
        task.archiveName = "${project.name}-${variant.baseName}-${version}.jar"
        artifacts.add('archives', task);
    }
}

task sourcesJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier = 'sources'
}

artifacts {
    archives sourcesJar
}

} else {

apply plugin: 'java'
apply plugin: 'maven'

sourceCompatibility = JavaVersion.VERSION_1_7
targetCompatibility = JavaVersion.VERSION_1_7

install {
    repositories.mavenInstaller {
        pom.artifactId = 'XxxxXxxx'
    }
}

    task execute(type:JavaExec) {
       main = System.getProperty('mainClass')
       classpath = sourceSets.main.runtimeClasspath
    }
}

dependencies {
    compile 'io.swagger:swagger-annotations:1.5.8'
    compile 'com.squareup.okhttp:okhttp:2.7.5'
    compile 'com.squareup.okhttp:logging-interceptor:2.7.5'
    compile 'com.google.code.gson:gson:2.6.2'
    compile 'joda-time:joda-time:2.9.3'
   // testCompile 'junit:junit:4.12'
}

Am I doing something complete wrong here? What is the correct way to implement swagger-codegen code into my project?

You could clone the Android swagger-codegen example.

(which does use Junit, so I'm not sure what error you got)

Unless that's what you mean by

So far I tried to copy the source and merge the two gradle build files

To which, I ask, what two Gradle files? It looks like you merged an Android Gradle file with a Java Gradle file, which seems to causing more issues because you are getting...

The 'java' plugin has been applied, but it is not compatible with the Android plugins.

Which seems pretty self explanatory when you have this line

apply plugin: 'java'

It's not too clear what you are trying to do here other than check the build target

if(hasProperty('target') && target == 'android')

回答2:

The swift way to import it was to compile the swagger generated project then copy the .jar file to my android project and add its as a library.
