java - 使用 ProGuard 将字节码转换为 dex 时出错

Question

没有 multidex 出现此错误:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: Return code 1 for dex process

启用 multidex 后:

Error:Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: Error while executing java process with main class com.android.multidex.ClassReferenceListBuilder with arguments {C:\Users\pah-to-app\app\build\intermediates\multi-dex\debug\componentClasses.jar C:\Users\pah-to-app\app\build\intermediates\transforms\proguard\debug\jars\3\1f\main.jar}

这是我的 gradle 文件:

   apply plugin: 'com.android.application'

    android {
        compileSdkVersion 27
        buildToolsVersion "27.0.2"
        defaultConfig {

            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
            javaCompileOptions {
                annotationProcessorOptions {
                    includeCompileClasspath false
                }
            }
            vectorDrawables.useSupportLibrary = true

        }
        buildTypes {
            release {
                minifyEnabled true
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
            debug {
                minifyEnabled true
                shrinkResources true
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        compile 'commons-io:commons-io:2.4'
        compile 'com.android.volley:volley:1.0.0'
        compile 'com.squareup.picasso:picasso:2.5.2'

        compile 'com.android.support:support-vector-drawable:27.0.2'
        compile 'com.android.support:design:27.0.2'

        compile 'com.android.support.constraint:constraint-layout:1.0.2'
        compile 'com.github.castorflex.smoothprogressbar:library:1.1.0'
        testCompile 'junit:junit:4.12'
    }
apply plugin: 'com.google.gms.google-services'

期待您提出有用的建议来解决此问题。谢谢。
