Eclipse JGit : Basic authentication using a password to Git is deprecated and will soon no longer work

 I have recently received an email from GitHub saying :

You recently used a password to access the repository at [my GitHub repo] with git using JGit/5.3.0.201903130848-r.

Basic authentication using a password to Git is deprecated and will soon no longer work. Visit https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information around suggested workarounds and removal dates.

I got this because I allowed JGit plugin of Eclipse to access my GitHub repo using password. To resolve this I need to configure Eclipse JGit to use token instead of password.

Here how it is done.

1) Go to New personal access token (github.com) and generate a new token with required scopes.

2) In Eclipse | [Your Project] go to Repositories View

3) Go to Remotes | Origin | Right click on the URL | Change Credentials

Now set the token instead of password in the password field.

That's all.

Gradle build failed in eclipse : Could not create an instance of type eclipsePlugin

I upgraded my Eclipse IDE to version 2020-12 (4.18.0) and started to get Gradle build error after launching the IDE.

In Eclipse console it showed this error:

---

FAILURE: Build failed with an exception.

* What went wrong:

Could not create an instance of type eclipsePlugin_5gol6cepvkmdl1guwpr4mu03j.

> Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

In Eclipse Problems tab it showed: 

Could not run build action using Gradle distribution 'https://services.gradle.org/distributions/gradle-5.2.1-bin.zip'.

Could not create an instance of type eclipsePlugin_5gol6cepvkmdl1guwpr4mu03j.

Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

---

Solution:

The solution of the problem is simply upgrading Gradle. Previous gradle version was 5.2.1, then I upgraded to version 6.7.1 and got it resolved.

For gradlew wrapper, file gradle-wrapper.properties needs to be modified to update distributionUrl. This file is located at Project Root | gradle | wrapper.

distributionUrl=https\://services.gradle.org/distributions/gradle-6.7.1-bin.zip.

After the update, gradlew clean build command will download the new gradle version and the problem will be resolved.
