How to resolve the Received fatal alert: protocol_version ? My java version is 1.7 and maven version is 3.3.3

Answer 1

On my new laptop (Win10) I have downgraded maven 3.8.7->3.6.3 and jdk 19->1.8
Maven 3.8.7 is blocking a lot of old repositories, one sometimes does need.

Answer 2

I had the same issue, I tried most of the answers here but still did not work. My issue was Proxy settings on my IDE. So it is also important to remember to check proxy settings. File > Settings > System Settings > HTTP Proxy - Select Auto-Detect proxy settings

Answer 3

The Package you are trying to install doesn't support TLS1.1 and you might be by default using TLS 1.1. Configure your Java runtime to enable TLS 1.2 by adding -Dhttps.protocols=TLSv1.2 to your Maven Build command would solve the problem.

For Example: mvn clean install -Dhttps.protocols=TLSv1.2

Answer 4

I resolved this error in SpringToolSuit by adding settings.xml file in .m2 folder which is located in Users folder of C drive and by updating Project by right click on pom.xml -> Maeven -> Update Project.

Make sure you select Force update of snapshots/releases.

Answer 5

In my case the automatic update of maven dependencies were disabled in eclipse.
Solution:
Go to Windows->Preferences->Maven
and uncheck the check box

"Do not automatically update dependencies from remote repositories"

Then update the project
Right click on project->maven->update project

Answer 6

It needs both : Configuring the JVM runtime arguments as well as having a settings.xml, after I did both it worked. Updating only the JVM runtime argument did not help.

Answer 7

I had upgraded from Java 1.7 to Java 1.8 and got the same error. To resolve this error, I checked the mvn version using mvn -version and found that JAVA_HOME was still using the Java 1.7. I changed the JAVA_HOME in the environment variable to point to Java 1.8 jre in JDK

Hope this helps someone.

Answer 8

The simplest solution is to configure your JVM runtime arguments. On eclipse, you can do it as following :

go to windows>preferences>java>installed JREs click on the Intalled JRE/JDK you are using for your project

click on "edit" on le right, and add -Dhttps.protocols=TLSv1.2 in the Default VM arguments Input field.

see the screenshot :

Answer 9

I set my settings.xml file in the .m2 directory just as the one here: https://github.com/alipay/sofa-rpc/pull/190/files

Then exec mvn install and all dependencies started to download. I haven't had a settings.xml file before and I am not using any proxy. Hope it helps somebody.

PD. I have jdk 1.7 and Maven 3.3.9

Answer 10

Sonatype no longer supports TLSv1.1 and below (effective, June 18th, 2018). My guess is that you are using TLSv1.1 protocol or below.

The documentation I listed gives you 4 options:

1. Upgrade your Java runtime, for example with OpenJDK builds or Oracle paying support
2. Configure your Java runtime to enable TLS 1.2 by adding -Dhttps.protocols=TLSv1.2
3. Use a repository manager that uses a Java version supporting TLS 1.2
4. Revert back to http until you can acheive one of the above remediation steps.

I fixed it myself by just using -Dhttps.protocols=TLSv1.2 as a VM argument.  

Answer 11

For a permanent solution(mostly required in Java 7) - in you build directory(where you do the mvn command from) add directory:

.mvn (in cmd mkdir .mvn)

and in it create file

jvm.config

and in put the following line:

-Dhttps.protocols=TLSv1.2
