我正在尝试运行我的应用程序，但此错误出现在我的终端中。我以前在sdk上遇到一些问题，我正在更改build.gradle文件。

apply plugin: 'com.android.application'

android {
    compileSdkVersion rootProject.findProperty("android.compileSdkVersion") as Integer
    defaultConfig {
        targetSdkVersion findProperty("android.targetSdkVersion") as Integer
        minSdkVersion findProperty("android.minSdkVersion") as Integer
        applicationId findProperty("android.applicationId")
        versionCode findProperty("android.minSdkVersion") as Integer
        versionName findProperty("android.versionName")

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

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

dependencies {
    implementation 'com.android.support:appcompat-v7:30.0.0'
    implementation(name:'projA', ext:'aar')
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

如果你有什么建议，我能做什么，请帮我。
