更新 Android Studio 3.1 Canary 6

的版本后,我收到错误消息

在成功运行之前,我不知道为什么会发生这种情况。

主要错误是:

有什么解决方案吗?

答案 0 :(得分:117)

  • 我的解决方案很简单,请不要查看构建 - 运行任务中的错误通知(这应该是执行失败的任务':app:compileDebugJavaWithJavac&# 39)

  • 只需修复其下方 Java编译器部分中的所有错误。

答案 1 :(得分:14)

我有类似的问题,并且在“编译”中没有显示任何错误。我尝试清理和重建没有任何成功。我通过使用菜单文件中的 Invalidate Caches / Restart (使缓存/重新启动无效)找到了问题,重新启动后,我设法看到了编译错误。

答案 2 :(得分:6)

我发现解决方案是 Android Studio 3.1 Canary 6

的问题

我对 Android Studio 3.1 Canary 5 的备份对我有用,并保存了我的半天。

现在我的 build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.2'
    defaultConfig {
        applicationId "com.example.demo"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    dataBinding {
        enabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:design:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:support-v4:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:recyclerview-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:cardview-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.squareup.retrofit2:retrofit:2.3.0"
    implementation "com.google.code.gson:gson:2.8.2"
    implementation "com.android.support.constraint:constraint-layout:1.0.2"
    implementation "com.squareup.retrofit2:converter-gson:2.3.0"
    implementation "com.squareup.okhttp3:logging-interceptor:3.6.0"
    implementation "com.squareup.picasso:picasso:2.5.2"
    implementation "com.dlazaro66.qrcodereaderview:qrcodereaderview:2.0.3"
    compile 'com.github.elevenetc:badgeview:v1.0.0'
    annotationProcessor 'com.github.elevenetc:badgeview:v1.0.0'
    testImplementation "junit:junit:4.12"
    androidTestImplementation("com.android.support.test.espresso:espresso-core:3.0.1", {
        exclude group: "com.android.support", module: "support-annotations"
    })
}

和我的 gradle 是:

classpath 'com.android.tools.build:gradle:3.1.0-alpha06'

及其最终的工作。

我认为 Android Studio 3.1 Canary 6

中存在问题

谢谢大家的时间。

答案 3 :(得分:4)

我在 Android Studio 3.1 Build#AI-173.4670197,建于2018年3月22日 JRE:1.8.0_152-release-1024-b02 amd64 JVM:JetBrains s.r.o的OpenJDK 64位服务器VM Windows 10 10。

我遇到了同样的问题,只有在将build.grade文件更改为

后才能使用
    compileOptions {                                                          
    sourceCompatibility JavaVersion.VERSION_1_8 
    targetCompatibility JavaVersion.VERSION_1_8


}

在此更改之前,没有任何工作,所有编译都会失败。以前我的设置是

sourceCompatibility JavaVersion.VERSION_1_7 
targetCompatibility JavaVersion.VERSION_1_8

答案 4 :(得分:2)

尝试将buildToolVersion更新为27.0.2而不是27.0.3

由于构建工具的兼容性问题,可能会发生错误

答案 5 :(得分:1)

我通过从项目中删除“ /。idea / libraries” 解决了该问题。谢谢

答案 6 :(得分:1)

这对我有用!

App / build.gradle

//添加它。...保持两个版本相同

compileOptions {                                                          
    sourceCompatibility JavaVersion.VERSION_1_8 
    targetCompatibility JavaVersion.VERSION_1_8
} 

答案 7 :(得分:0)

转到首选项(设置):点击构建,执行,部署.....然后选择:即时运行......并取消选中其最顶层的复选框(即禁用即时运行)

答案 8 :(得分:0)

只需解决来自Java编译器而不是Build-Run任务的问题

答案 9 :(得分:0)

不确定该解决方案是否对您有用,只是想让您了解编译器和构建工具的版本兼容性问题。

这可能是因为Java和Gradle版本不匹配。

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

Gradle 4.4仅与Java 7和8兼容。因此,将全局变量JAVA_HOME指向Java 7或8。

在Mac中,将以下行添加到您的 〜/ .bash_profile

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_191.jdk/Contents/Home

您可以有多个Java版本。只需根据需要更改JAVA_HOME路径。您可以轻松做到,check this

答案 10 :(得分:0)

此问题通常与Java代码中的编译器错误有关。有时,Android Studio不会在Project explorer中显示这些错误。但是,当打开有问题的.java文件时,将显示错误。尝试解决错误并重建项目。

答案 11 :(得分:0)

在选择1.8 Java版本的“目标兼容性”后,我已经解决了此问题。文件->项目结构->模块。

答案 12 :(得分:0)

我遇到了同样的问题,我可以通过将JDK 11切换到JDK 8来解决。
