Android Studio 模块 gradle 全新安装给出错误 com.android.volley 不存在

Question

场景

我正在尝试创建我的第一个 android 库，它是 Volley 的扩展，并为 Django REST Framework APIs 集成提供类。没有浏览量，只有 Java 类.

这是我的依赖项在模块中的样子：

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0'
    testImplementation 'junit:junit:4.12'
    implementation 'com.android.volley:volley:1.1.1'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

我在模块应用程序中构建 gradle 时没有遇到任何错误。

当我执行 gradle 任务时：clean install，出现以下错误

错误

12:12:38 PM: Executing tasks 'clean install'...

Executing tasks: [clean, install]

我一直在网上搜索，但没有成功！以前有人遇到过这个错误吗？我做错了什么？

Answer 1

问题出在 Javadoc 的生成中。 javadoc 中存在非 ASCII 字符会导致此问题。要解决此问题，您应该使用以下代码段禁用它。当我查看你的项目源代码时，你应该将它添加到你的 bintray_script 文件中。

tasks.withType(Javadoc) {
    enabled = false
}

Answer 2

也许您在 Google 上搜索了错误的关键字。如果您要修复 javadoc 而不是跳过它，这会有所帮助。我做了一些研究并找到了解决方案。

afterEvaluate {
    javadoc.classpath += files(android.libraryVariants.collect { variant ->
        variant.javaCompiler.classpath.files
    })
}

这是

我也在GitHub上推送了解决方案。
