如何修复 > 没有方法签名：build_dxc6m5s863o0nfrfjdg2bqjp.android() 适用于参数类型

Question

问题：评估项目 ':app' 时出现问题。

没有方法签名：build_dxc6m5s863o0nfrfjdg2bqjp.android() 适用于参数类型：(build_dxc6m5s863o0nfrfjdg2bqjp$_run_closure1) 值：[build_dxc6m5s863o0nfrfjdg2bqjp$_run_closure1@18112963]

Gradle 文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.numix.calculator_pro"

        testApplicationId "com.numix.calculator_pro_pro.pro.tests"
        testInstrumentationRunner "android.test.InstrumentationTestRunner"
    }

    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }

    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    implementation 'com.android.support:support-v4:21.0.3'
    compile files('libs/achartengine.jar')
    compile files('libs/ejml-0.21.jar')
    compile files('libs/arity-2.1.6.jar')
    compile files('libs/slider.jar')
    compile files('libs/acra-4.5.0-sources.jar')
    compile files('libs/acra-4.5.0-javadoc.jar')
}

检查 build.gradle 中是否存在 versionCode 变量，它是整数，而不是字符串：

defaultConfig {
    //....
    versionCode 15
    versionName "1.15"
}
