I try adding

        <artifactId>slf4j-api</artifactId>
        <version>1.7.32</version>
    </dependency>

to pom.xml but didn’t work. I’m using Eclipse Version: 2024-06 (4.32.0) Build id: 20240606-1231, Java jdk 1.8.0_361. Can please someone help me with this.

2

Do you have an extended maintenance support contract?

3

How can I check that?

4

Probably a better question for your accounting department ;)

5

Is that why I cannot perform the migration or get a response?

6

Edit: it’s published on Maven Central but required an Extended Maintenance support contract.

7

It looks like you have some network problems.

8

Yes, either that or firewall blocking access to the maven central. If your Vaadin 7 build works, it may be due Vaadin artefacts being in your .m2 folder because maven managed to load them in the past or you have them in the local nexus. Anyways, without Extended Maintenance subscription you can upgrade to Vaadin 8.14.3. If you need the newer versions, contact our sales for more details.

9

I tried deleting .m2 folder and set new URL for central repository same error.

<mirror>
  <id>central-secure</id>
  <url>https://repo.maven.apache.org/maven2/</url>
  <mirrorOf>central</mirrorOf>
</mirror>

Any suggestions?

10

What maven version are you using?

11

I’m trying to migrate on Vaadin version 8.14.1

12

I mean the Maven version, not the Vaadin version.
What do you get executing mvn --version?

Also, mvn help:effective-pom should show all used repositories. It might help to understand why maven is trying to contact the no more existing repository.

The mirror you defined in the settings.xml should work, but only if the mirrorOf value matched the wrong repository id

13

I’m using Apache Maven 3.9.6

14

Do you still get java.net.UnknownHostException or some other error? UnknownHostException is expected for central.maven.org since that domain name doesn’t exist but it should not be the case for repo.maven.apache.org which for me resolves to 151.101.244.215.

15

Still getting same errors i tried to migrate to 8.0.0 same error

Can you please run mvn help:effective-pom and post the output?

17

Also, the following log is suspicious

It looks like the HOME environment variable is not set when the migration tool is executed. Can you check if the env var is set and, if not, export it before running the maven command?

18

It seems you are running vaadin-maven-plugin 8.0.0.

You should try with a recent version, e.g. 8.25.0
