Compiler error “archive for required library could not be read” - Spring Tool Suite

Question

I am starting to configure my development environment and I am using Spring Tool Suite 2.8.1 along with m2E 1.01.

As far as I can tell, since this is a Maven Project

Answer 1

When I got an error saying "archive for required library could not be read," I solved it by removing the JARS in question from the Build Path of the project, and then using "Add External Jars" to add them back in again (navigating to the same folder that they were in). Using the "Add Jars" button wouldn't work, and the error would still be there. But using "Add External Jars" worked.

Answer 2

In case of VSCode, follow the below steps:

1. Navigate to the respective folder that contains the corrupted jar
2. Delete just the jar
3. mvn clean
4. mvn compile

That worked for me.

Answer 3

Remove maven dependenices from build path

Answer 4

Alternatively, below commands also worked for me:

mvn -s settings.xml eclipse:clean
mvn -s settings.xml eclipse:eclipse

Answer 5

I deleted the local maven repository. Then just rightclick the project -> Maven -> Update Project... Select all concerned projects and click OK.
