【问题描述】：

当我尝试向我的应用程序的 gradle 文件中添加 Contentful 的实现时遇到此错误

Type com.google.gson.ExclusionStrategy is defined multiple times

看起来我的中间 dex 文件中的某些内容正在发生。这是完整的错误：

Error: /Users/ceddings/StudioProjects/r15-android-rms-kiosk-launcher/kiosk/build/intermediates/mixed_scope_dex_archive/debug/out/2fcf9ca3ebe4bba6e5de15039706dbd823b837def40fd130c6d32dbf72d7d3fe_1.jar:classes.dex, Type com.google.gson.ExclusionStrategy is defined multiple times: /Users/ceddings/StudioProjects/r15-android-rms-kiosk-launcher/kiosk/build/intermediates/mixed_scope_dex_archive/debug/out/2fcf9ca3ebe4bba6e5de15039706dbd823b837def40fd130c6d32dbf72d7d3fe_1.jar:classes.dex, /Users/ceddings/StudioProjects/r15-android-rms-kiosk-launcher/kiosk/build/intermediates/mixed_scope_dex_archive/debug/out/1c3715710bef6d11c4bd58c73e056adcb809f2dac72c25d60ee538a9010444f0_1.jar:classes.dex

以下是我的 gradle 文件。我该如何解决这个问题？

implementation project(':scanner')

【参考方案1】：

我也遇到了同样的问题，我猜你应该删除build.gradle文件中的“exclude group: 'com.google.code.gson', module: 'gson', 看看里面的settings.gradle文件项目根目录类似并删除文件....

【参考方案2】：

删除与C/Users/ceddings/StudioProjects/r15-android-rms-kiosk-launcher/kiosk/build/intermediates/mixed_scope_dex_archive/debug/out/1c3715710bef6d11c4bd58c73e056adcb809f2dac72c25d60ee538a9010444f0_1.jar:classes.dex 对应的位置的文件为我解决了这个问题。

【参考方案3】：

以上所有答案都不适合我。

app/build.gradle 配置 all*.exclude module:'gson' //去除重复依赖： gson

这会起作用。
