android - 无法将 XStream 文件依赖项添加到 Android Studio 项目

Question

我已经下载 xstream-1.4.8.jar 并将其添加到我的 Android Studio 项目中。当我构建项目时它工作正常但是当我尝试运行它时我从 Gradle Build 窗口中收到以下错误:

我已经查看了此处的相关答案，但建议的解决方案均不适合我。

提前致谢。

Answer 1

XStream 1.4.8 是为 Java 8 编译的，Android 支持的最新版本是 Java 7。

一种解决方案是使用适用于 Android 的 XStream 1.4.7，另一种是下载 XStream 1.4.8 源代码并自行编译。在这种情况下，您将不得不删除 LambdaMapper.java 和可能的其他一些有问题的类。

您还可能会遇到使用不同版本的 xmlpull 解析器的问题。在这种情况下，您可以从编译中排除一个。

compile('com.thoughtworks.xstream:xstream:1.4.7') {
    exclude group: 'xmlpull', module: 'xmlpull'
}
