Travis CI couldn't install openjdk11

Question

I have a problem with installing openjdk11 in Travis CI.

This is the error I'm getting

Installing openjdk11
$ export JAVA_HOME=~/openjdk11
$ export PATH="$JAVA_HOME/bin:$PATH"
$ ~/bin/install-jdk.sh --target "/home/travis/openjdk11" --workspace "/home/travis/.cache/install-jdk" --feature "11" --license "GPL" --cacerts

The command "~/bin/install-jdk.sh --target "/home/travis/openjdk11" --workspace "/home/travis/.cache/install-jdk" --feature "11" --license "GPL" --cacerts" failed and exited with 51 during .
Your build has been stopped.

.travis.yml file:

  directories:

Answer 1

To avoid this problem, try something like this in your .travis.yml configuration file:

language: java
dist: xenial
sudo: required

jdk:
  - openjdk11
