I have created a Spring Boot project from https://start.spring.io/ using gradle.

Now when I try to import the project in Spring Tool Suite Version: 3.9.6.RELEASE, I am getting the error as

org.gradle.tooling.GradleConnectionException: Could not create an instance of Tooling API implementation using the specified Gradle installation '/usr/share/gradle'.

Gradle version I am using is

------------------------------------------------------------

Gradle 4.4.1

------------------------------------------------------------



Build time:   2012-12-21 00:00:00 UTC

Revision:     none



Groovy:       2.4.15

Ant:          Apache Ant(TM) version 1.10.5 compiled on August 27 2018

JVM:          11.0.1 (Oracle Corporation 11.0.1+13-Ubuntu-2ubuntu1)

OS:           Linux 4.18.0-13-generic amd64

I am using Buildship Gradle Integration 3.0 STS plugin.
Is it some version issue or what wrong I am doing?

I had a similar error :

org.gradle.tooling.GradleConnectionException: Could not create an instance of Tooling API implementation using the specified Gradle distribution 'https://services.gradle.org/distributions/gradle-4.10.1-all.zip'.

...

Caused by: java.lang.ExceptionInInitializerError

...

Caused by: java.lang.ClassCastException: org.slf4j.impl.Log4jLoggerAdapter cannot be cast to org.gradle.api.logging.Logger

...

I searched my whole system for "slf4j" and found two very old .jar files in /usr/java/packages/lib/ext/. Removing them allowed me to build my project.

I suspect your problem is that you have to add slf4j jar files, since I had a "ClassCastException" and you had a "ClassNotFoundException".
