Plugin [id: 'org.jetbrains.kotlin.jvm', version: '1.2.71'] was not found in any of the following sources

Check your Internet connection and make sure your Internet is not restricted.

I solved this problem by turning on proxy for all tunnels (not just HTTP) with a VPN app.

(1) in my case (OpenJDK 11 on Ubuntu 18.04) the problem was Gradle not being able to download the POM file from gradle plugin-server. you can test it by entering this line into jshell:

new java.net.URL("https://plugins.gradle.org/m2/org/jetbrains/kotlin/jvm/org.jetbrains.kotlin.jvm.gradle.plugin/1.3.11/org.jetbrains.kotlin.jvm.gradle.plugin-1.3.11.pom").openStream()

(you can find your url by running gradle with --debug option)

So if you received an exception like this: InvalidAlgorithmParameterException: trustAnchors parameter must be non-empty then the trouble is CA-certs cache. which could be easily fixed by writing these lines into bash Ref:

sudo su
/usr/bin/printf '\xfe\xed\xfe\xed\x00\x00\x00\x02\x00\x00\x00\x00\xe2\x68\x6e\x45\xfb\x43\xdf\xa4\xd9\x92\xdd\x41\xce\xb6\xb2\x1c\x63\x30\xd7\x92' > /etc/ssl/certs/java/cacerts
/var/lib/dpkg/info/ca-certificates-java.postinst configure

By the way do not forget to restart gradle daemon before trying again. (gradle --stop)

(2) another reason could be your internet not having access to bintray.com (the internet of Iran or China) which you can test by putting this line on jshell :

new java.net.URL("https://jcenter.bintray.com/org/jetbrains/kotlin/kotlin-gradle-plugin-api/1.3.11/kotlin-gradle-plugin-api-1.3.11.pom").openStream()

If you received a connection timeout, it confirms this theory. In this case you need to buy and have proxy/vpn connected in order to be able to download these dependencies.
