Maven has packages locally but cannot be introduced.

Maven has packages locally but cannot be brought in

If the required package exists locally but cannot be introduced, please follow these steps to resolve the issue:

1. Make sure that the package exists in your local Maven repository

By default, Maven will store the downloaded dependency package in{}/.m2/repositoryin the directory.

You can check whether the package exists by browsing this directory.

2. Check your files

Make sure you correctly add the dependencies for the required package.

Can be passed independenciesAdd the following code to the tag to add dependencies:

&lt;dependency&gt;
&lt;groupId&gt;PackedgroupId&lt;/groupId&gt;
&lt;artifactId&gt;PackedartifactId&lt;/artifactId&gt;
&lt;version&gt;Packed版本&lt;/version&gt;
&lt;/dependency&gt;

3. Check if your project is correctly built in Maven

Run in the project root directorymvn clean installCommands to ensure that Maven downloads and installs dependencies correctly.

4. If the package does exist in your Maven repository

But it still cannot be introduced, probably because of problems with Maven's local cache.

In this case, you can try to clear Maven's local cache.

Run on the command linemvn dependency:purge-local-repositoryCommand to clear Maven's local cache.
Rerunmvn clean installCommands to re-download and install dependencies.

5. If none of the above steps can solve the problem

You can try to delete the entire local Maven repository and then run it againmvn clean installCommand to re-download and install all dependencies.

When deleting a repository, make sure to back up important dependencies.
