Building the examples

Dependencies

The CloudHSM Client and JCE dependencies are required. They should be installed using the official procedures documented here:

• https://docs.aws.amazon.com/cloudhsm/latest/userguide/java-library-install.html

The examples are tested on a fresh Amazon Linux 2 AMI. You will need to have the following packages installed:

• OpenJDK 8
• Apache Maven 3.0.5

You can install these packages on Amazon Linux 2 by running

sudo yum install -y java maven

If you are running on Amazon Linux 1, you will need to install extra packages to get Maven. You can follow these instructions to build the samples on Amazon Linux 1:

# Maven is only available through extra packages
sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo

# You will need Java 1.8 to build the samples
sudo yum install -y java-1.8.0-openjdk-devel
sudo yum install -y apache-maven

# When updating alternatives, choose the 1.8 path: /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java
sudo update-alternatives --config java

Building

You can build the project using Maven. Maven will copy the required CloudHSM jars into a local repository and build fat jars which can be executed from the command line. These fat jars will be placed in the target/assembly/ directory. To build the project, use the following command:

mvn validate
mvn clean package

Running the samples

You will need to have a CloudHSM Client connected to an ACTIVE cluster. For more details, please follow the official instructions here:

• https://docs.aws.amazon.com/cloudhsm/latest/userguide/getting-started.html

All Java dependencies should be bundled in the fat jars. You will only need to specify the location of the native library in /opt/cloudhsm/lib. Jars can be run using the following command line (as an example):

java -ea -Djava.library.path=/opt/cloudhsm/lib/ -jar target/assembly/login-runner.jar --help

Running and verifying all the samples

To run and verify all the samples together, run the command mvn verify
