本文介绍了如何解决“序言中不允许内容”？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

我已经检查了所有xml文件，但找不到任何不适当的地方。我已经重建了项目。我已使缓存无效并重新启动。我已经在应用模块上进行了分析操作，但没有任何反应。

I have checked all my xml files and couldn't find anything out of place. I've rebuilt project. I've invalidated the cache and restarted. I've rn the analyze operation on the app module and nothing came up.

不确定如何找到问题。

我认为这是相关的日志，但是我不确定

I think this is the relevant log but I am not sure what to do with that.

TH是在我安装了studio建议的一些更新后发生的

THis happened after I've installed some updates suggested by studio for the studio itself, gradle and emulator.

编辑：根据CommonsWare的建议修复文件后，它再次失败。我认为这是日志的重要部分。我应该卸载并重新安装Android Studio吗？

after fixing the file according to CommonsWare suggestion, it fails again. I think this is the important part of the log. SHould I just uninstall and reinstall Android Studio?

推荐答案

该下载一定失败。可能有一种方法可以迫使Gradle重新下载它认为已经存在的依赖项，但是我不确定如何做到这一点。

Something must have failed with that download. There may be a recipe to force Gradle to re-download dependencies that it thinks that it already has, but I am not certain how to do that.

尝试用以下命令替换该POM文件：

The simple thing to try to is to replace that POM file with:
