:: app：processDebugResources的executeTaskAction失败

时间：2019-01-03 18:01:41

标签： android-studio

我收到此错误消息：构建：构建失败->运行构建->运行任务->：app：processDebugResources-> executeTaskAction。下面显示的代码顺序为：错误消息，然后是build.gradle（Project），然后是build.gradle（app）。

其他StackOverflow用户之前已经多次回答过此错误消息，但是他们提出的解决方案中没有一个对我有用。主要是因为他们使用的版本建议我修复build.gradle（Project：app）中的“ com.android.support:appcompat-v7:28.0.0”设置，但是它们的版本不同，因为这些帖子来自2+几年前。我试过清理项目，清理构建，重新构建构建和项目，添加“ Maven”存储库，重新安装所有的Sdks……在过去的三个小时中没有任何工作。

这是错误消息：

这是我的build.gradle（Project）中当前的内容：

//顶层构建文件，您可以在其中添加所有子项目/模块共有的配置选项。

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'


   // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    }
 }

allprojects {
    repositories {
       google()
         maven {
            url "https://maven.google.com"
        }
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是我的build.gradle（Module：app）; 

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.artchen_wei.synthesizer"
        minSdkVersion 22

        versionName "1.0"
        testInstrumentationRunner 
"android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard- 
  android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint- 
layout:1.1.3'
    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'
 }

我正在尝试使构建的所有步骤有效运行，以便我可以完成此任务。

答案 0 :(得分：0)

查看您的错误消息（有点隐藏在大堆栈跟踪中，但是应该  在IDE同步窗口顶部）：

  

错误：无效的符号名称       'com.example.firstname_lastname.synthesizer：id / null'。

这意味着您将在资源中的某个位置定义一个名称为“ null”的ID。它可以位于具有+id/null构造的任何XML文件中，也可以位于具有<id name="null ... />或<item type='id' name='null' ... />的values文件夹中。

在项目中搜索单词null，您应该可以找到它。由于单词null是一个非法名称（即您不能在Java中将它用作变量名），因此只需将其重命名为其他名称，例如not_null。确保不要使用任何其他非法关键字，例如public，private，final，default等。
