问题是什么？
回答by Ilya
The problem is in file ecommerce-web/maven-metadata-local.xml, it contains char(0)(or nullchar, or Unicode: 0x0).
Clean all local repository, or delete folder with com.app:ecommerce-webartifact
问题出在 file 中ecommerce-web/maven-metadata-local.xml，它包含char(0)（或nullchar，或 Unicode: 0x0）。
清理所有本地存储库，或删除带有com.app:ecommerce-web工件的 文件夹
There is nothing in my maven-metadata-local.xml
我的 maven-metadata-local.xml 中没有任何内容
It's not true. Open your file with Notepad++ and you will see many nulls
这不是真的。用记事本打开文件++和你会看到许多null小号
回答by RTS
Just go under
就下
C:\Users\admin\.m2\repository\com\app\ecommerce-web\
and delete maven-metadata-local.xmlThen do a clean install one more time, this should fix the problem and that's what I did.
并删除maven-metadata-local.xml然后再进行一次全新安装，这应该可以解决问题，这就是我所做的。

It's because of character encoding issue. It doesn't appear when we open file in UTF-8encoded format.
这是因为字符编码问题。当我们以UTF-8编码格式打开文件时，它不会出现。
To mitigate this issue, open file in notepad++and select encoding as "Encode in ANSI". You will see many BOM characters. Remove them manually and save it again. It works.
要缓解此问题，请在notepad++ 中打开文件并选择编码为“在 ANSI 中编码”。您将看到许多BOM 字符。手动删除它们并再次保存。有用。

I also had this experience. The simple solution was deleting the relevant content of the .m2folder and local repofolder and build again using mvn clean install(Please make sure backup your important data :))
我也有过这样的经历。简单的解决方案是删除.m2文件夹和本地 repo文件夹的相关内容，然后使用mvn clean install重新构建（请确保备份您的重要数据:)）

Please backup your .m2 file when it working properly. In case you get above mentioned issue. you can replace the .m2 file which you have got backup. The issue can happen when corrupt the m2 file when occur the power cut kind of issue in advance. Then you wont get same issue again and again.
请在它正常工作时备份您的 .m2 文件。如果您遇到上述问题。您可以替换已备份的 .m2 文件。当提前发生停电类型的问题时，损坏 m2 文件时可能会发生此问题。那么你就不会一次又一次地遇到同样的问题。
