missing jdk when using java-1.8.0-amazon-corretto

Question

I have this error:

Could not find tools.jar. Please check that /usr/lib/jvm/java-1.8.0-amazon-corretto.x86_64/jre contains a valid JDK installation.

in the cloudformation template, i have:

        extras:
          commands:
            'a_enable_docker':
              command: 'amazon-linux-extras enable docker=18.06.1'
              test: "! grep -Fxq '[amzn2extra-docker]' /etc/yum.repos.d/amzn2-extras.repo"
            'b_enable_corretto8':
              command: 'amazon-linux-extras enable corretto8'
              test: "! grep -Fxq '[amzn2extra-corretto8]' /etc/yum.repos.d/amzn2-extras.repo"
        install:
          packages:
            rpm:
              jenkins: 'https://pkg.jenkins.io/redhat-stable/jenkins-2.176.3-1.1.noarch.rpm'
            yum:
              'java-1.8.0-amazon-corretto': []
              'ruby': []

so, java is installed,

[root@ip-10-1-15-79 ~]# java -version
openjdk version "1.8.0_222"

Answer 1

You need to use java-1.8.0-amazon-corretto-devel to get the JDK, without that trailing devel it's just a JRE
