jjwt Consumer Example

This is an example project that is using jjwt. The purpose of this project is to help test usage of the jjwt jar. Since Java 9 is deprecating jaxb in the SE jdk, special care has to be taken for libraries that expect the jaxb classes.

Testing in Docker containers

You can skip the steps below if you have docker. Simply run the test-jdk*.sh scripts to test with the specified jdk. If you are on a Mac, you can just run the test scripts. If on Linux, you need to run the scripts as root or with sudo (docker requires root privilege).

Ex.

$ sudo ./test-jdk7.sh
ryan@ryan-linux:~/projects/jjwt-consumer-example$ sudo ./test-jdk7.sh

Prereqs for Mac

I did my testing in OS X. You can do the testing in the following sections in any OS as long as you have multiple versions of java and manually set your JAVA_HOME before running maven. I'm using jenv to manage my java & JAVA_HOME in these examples.

Enable jenv to work with mvnw if you haven't before: (otherwise, mvnw doesn't respect the version of java jenv is specifying) jenv/jenv#78

jenv enable-plugin export

Testing jjwt

Java 7

Set jdk1.7:

jenv local 1.7

Confirm the java version maven will use is 1.7:

./mvnw -version
Maven home: /Users/ryan/.m2/wrapper/dists/apache-maven-3.5.2-bin/28qa8v9e2mq69covern8vmdkj0/apache-maven-3.5.2
Java version: 1.7.0_51, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.13.1", arch: "x86_64", family: "mac"

Now build with java 7 (the maven profile to target 1.7 will kick in):

./mvnw clean verify
