构建 android 应用程序时出现问题,LeftShift 错误

Problem with building android app, LeftShift error

我在 android 工作室中遇到构建问题,我用蜂软件制作了一个 android 应用程序,当我尝试构建它时出现错误。

我已经尝试从 android studio 构建它并且我修复了所有版本问题以及除此错误之外的所有其他问题

Could not find method leftShift() for arguments [build_m0k5smvps1e1hvx1einev6dw$_run_closure1@34e45104] on task ':buildPythonDebug' of type org.gradle.api.DefaultTask.

我搜索了答案,但没有找到有用的东西

这是build.gradle

    buildscript {
repositories {
    jcenter()
    google()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.4.0'
}
}

task buildPythonDebug << {
exec {
    commandLine "voc -v -p app -o build/intermediates/classes/debug   app".split()
}
exec {
    commandLine "voc -v -p app_packages -o build/intermediates/classes/debug app_packages".split()
}
}

task buildPythonRelease << {
exec {
    commandLine "voc -v -p app -o build/intermediates/classes/release app".split()
}
exec {
    commandLine "voc -v -p app_packages -o build/intermediates/classes/release app_packages".split()
}
}
task run << {
exec {
    commandLine "adb shell am start -n com.example.HelloWorld/android.AppName".split()
}
}

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "25.0.2"

defaultConfig {
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
}
sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        res.srcDirs = ['res']
    }
}
}

project.afterEvaluate {
packageDebug.dependsOn buildPythonDebug
packageRelease.dependsOn buildPythonRelease
run.dependsOn installDebug
}

dependencies {
implementation 'com.android.support:appcompat-v7:25.3.1'
implementation 'com.android.support:recyclerview-v7:25.3.1'
}

task 改变它

来自:

task abc << {
    .
    .
}

至:

task abc {
     doLast {
        .
        .
     }
}
