Jenv’s ability to automatically switch Java versions for different projects is quite convenient. * openjdk64-11.0.9 (set by /Users/powers/Documents/code/my_apps/delta-examples/.java-version) Here’s the jenv versions output from the delta-examples project root directory: system You can clone the delta-examples repo with git clone cd into the directory, and run jenv versions to verify that the project is automatically using Java 11. java-version file in the root project folder. Use the jenv local openjdk64-11.0.9 command to set a given project to use Java 11 by default. You can also clone the deequ repo and verify that mvn test is working on that repo as well.
My machine is using Maven 3.6.3 with Java 8. You can type mvn -v to see the Maven version that’s being used. Clone the JavaSpark project with the git clone command.Ĭd into the project directory and run the test suite with mvn test. You can verify that your Maven installation is working properly by cloning a project and running the test suite. The which mvn command should return something like /Users/powers/.jenv/shims/mvn. Let’s use jenv to get a different version of Maven.Įnable the jenv Maven plugin with jenv enable-plugin maven and then run which mvn to verify that the mvn commands are being properly captured by a jenv shim. Similar to Java, we never want to run commands using the system Maven. Which mvn returns /usr/local/bin/mvn, which is the system version of Maven. The jenv versions command should now output this: system List the Java virtual machines with ls -1 /Library/Java/JavaVirtualMachines.Īdd Java 11 to jenv with jenv add /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home/. Remember that Java versions need to be manually added to jenv.

Here’s the command to install Java 11: brew cask install adoptopenjdk/openjdk/adoptopenjdk11. Jenv is correctly loaded Install Java 11 You should get output like this: JAVA_HOME variable probably set by jenv PROMPT Run jenv doctor to confirm your setup is good. Now any library that’s looking for the JAVA_HOME environment to be set won’t error out. Run echo $JAVA_HOME and verify that it returns something like /Users/powers/.jenv/versions/openjdk64-1.8.0.272. Set the environment variable by running these commands: jenv enable-plugin export Lots of Java libraries depend on having a JAVA_HOME environment variable set. This’ll make sure we avoid hitting the system Java version. Type cat /Users/powers/.jenv/version to see it’s just a file with a single line openjdk64-1.8.0.272Īll Java commands will be routed to Java 8 now that the global version is set. This command simply writes the version to the /Users/powers/.jenv/version file. Set the global Java version to Java 8 with jenv global openjdk64-1.8.0.265. jenv makes it easy to avoid using the system Java. It’s always good to avoid using system installed programming language versions (applies to Python and Ruby too). Find the exact name of the version with jenv versions.Ĭheck to make sure the javac -version and java -version commands are working. The exact command on your machine might be something slightly different like jenv global openjdk64-1.8.0.272. Set the global Java version on your computer with jenv global openjdk64-1.8.0.265.
List the Java virtual machines with ls -1 /Library/Java/JavaVirtualMachines.Īdd Java 8 to jenv with jenv add /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/. Once Java is downloaded, we need to manually add it to jenv. Here’s the latest command to install Java 8: brew cask install adoptopenjdk/openjdk/adoptopenjdk8.īrew cask install adoptopenjdk8 used to work, but now returns Error: Cask 'adoptopenjdk8' is unavailable: No Cask with this name exists.īrew cask install caskroom/versions/adoptopenjdk8 also used to work, but now returns Error: caskroom/versions was moved. Here’s the output on my machine /Users/powers/.jenv/shims:/Users/powers/.jenv/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin. jenv paths that are prepended to the standard PATH directories. Restart your Terminal, run echo $PATH, and verify the output contains.
