问题描述

更新Android Studio后，无法构建我的项目之一.错误消息是:

After I updated Android Studio, one of my projects cannot be built. The error message is:

Error:(20) error: unknown element <library> found.
Error:(20) unknown element <library> found.
Error:java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
Error:com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
Error:Execution failed for task ':app:processDebugResources'.
    > Failed to execute aapt

我的SDK版本是25.我试图使缓存无效并添加 distributionUrl = https://services.gradle.org/distributions/gradle-4.1-rc-2-all.zip ，他们俩都不适合我.

My SDK version is 25. I have tried to invalidate cache and add distributionUrl=https://services.gradle.org/distributions/gradle-4.1-rc-2-all.zip, and both of them don't work for me.

这是我的依赖项:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.4.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:support-v4:25.4.0'
compile 'de.hdodenhof:circleimageview:2.2.0'
testCompile 'junit:junit:4.12'

annotationProcessor "com.github.Raizlabs.DBFlow:dbflow-processor:${dbflow_version}"
compile "com.github.Raizlabs.DBFlow:dbflow-core:${dbflow_version}"
compile "com.github.Raizlabs.DBFlow:dbflow:${dbflow_version}"

compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:25.4.0'
compile 'com.android.support:design:25.4.0'

compile 'com.microsoft.projectoxford:face:1.3.0'
}

这是删除DBFlow之后的错误日志:

This is the error log after removing DBFlow:

Error:(20) error: unknown element <library> found.
Error:(20) unknown element <library> found.
Error:java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
