Gradle build > PKIX path building failed

Hi,

I am trying to create a Spring Boot application using gradle project. I was able to run java class successfully, but when I have added spring boot dependecy in build.gradle file then I am getting PKIX path building failed error. I have tried various approaches but nothing worked.
I am using jdk 1.8 and spring boot 2.7.10.
Gradle details :-

Gradle version: 8.2
Plugin version: 3.13.4

PKIX path building failed

means that there is a problem with establishing a secure HTTPS connection.
This can for example be because you need to use some proxy you did not configure, or some firewall or anti-virus aggressively intervening, or it could also be a broken or bad Java installation with which you run Gradle.

Thank you for responding.
I’ve installed JDK 8 (from Oracle) again and updated both JAVA_HOME and PATH. Could you please provide more details about what you mean by “need to use some proxy you did not configure”?
When I used the latest version of JDK 21 and Spring 3.x.x, it worked seamlessly without any errors. Therefore, it doesn’t appear to be a firewall or antivirus issue. There might be a compatibility concern between Java, Spring, and Gradle, but I’m uncertain as the error seems to be indicating a different direction.

That’s irrelevant if it worked with Java 21.
Maybe the Java 8 you downloaded is missing some essential trusted certificates or similar.
I’d recommend you download instead the latest Java 8 from Adoptium and try with that.
