maven install error - only whitespace content allowed before start tag and not \u0

Question

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.3.1:install (default-install) on project ecommerce-web: Failed to install metadat

Answer 1

Delete all folders under app folder C:\Users\admin.m2\repository\com\app and then clean build project

Answer 2

I also had this experience. The simple solution was deleting the relevant content of the .m2 folder and local repo folder and build again using mvn clean install (Please make sure backup your important data :))

Answer 3

It's because of character encoding issue. It doesn't appear when we open file in UTF-8 encoded format.

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.

Answer 4

The problem is in file ecommerce-web/maven-metadata-local.xml, it contains char(0) (or null char, or Unicode: 0x0).
Clean all local repository, or delete folder with com.app:ecommerce-web artifact

There is nothing in my maven-metadata-local.xml

It's not true. Open your file with Notepad++ and you will see many nulls

Answer 5

Just go under

C:\Users\admin\.m2\repository\com\app\ecommerce-web\

and delete maven-metadata-local.xml Then do a clean install one more time, this should fix the problem and that's what I did.

Answer 6
