• Java: JAVA_HOME and JAVA_OPTS
• Maven: MAVEN_HOME and MAVEN_OPTS

Windows

1. Open the Start menu, right-click My Computer and select Properties.

2. Click Advanced System Settings.

   

   To quickly show the System Properties > Advanced > Environment Variables from the Windows Run prompt, type SystemPropertiesAdvanced and press Enter.

3. In the System Properties > Advanced, click Environment Variables.

4. To add a new system environment variable, on the Environment Variables window, click New.

5. Add the following:

   • JAVA_HOME: C:\Program Files\Zulu\zulu-8-amd64
   • JAVA_OPTS: -Xmx1024m -Dsun.lang.ClassLoader.allowArraySyntax=true
   • MAVEN_HOME: C:\apache-maven-3.6.2
   • MAVEN_OPTS: -Xmx2548m -XX:ReservedCodeCacheSize=128m -Dsun.lang.ClassLoader.allowArraySyntax=true

   The values for the JAVA_HOME and MAVEN_HOME variables depend on the location where Java and Maven are installed. This location might differ from the default values provided.

6. Select the Path system variable, and click Edit.

7. Add the following variables at the end of the Path variable:

   ;%JAVA_HOME%\bin;%MAVEN_HOME%\bin;

Mac and Linux

1. Modify your ~\.bash_profile (if using Bash shell) or ~\.zshrc (if using zsh shell) in your home folder to set the required environment variables.

   export JAVA_HOME=$(/usr/libexec/java_home -v "1.8.0")
   export JAVA_OPTS="-Xmx1024m -Dsun.lang.ClassLoader.allowArraySyntax=true"
   export MAVEN_HOME=~/tools/apache-maven-3.6.2
   export MAVEN_OPTS="-Xmx2548m -XX:ReservedCodeCacheSize=128m -Dsun.lang.ClassLoader.allowArraySyntax=true"
   export PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin

2. Open a new terminal window and verify the installation as follows:

   $ java -version
   openjdk version "1.8.0_504"

Configure Maven settings.xml

With a Maven Repository Manager

A Maven repository manager is required for effective shared development. If your team has prepared the Maven repository manager then complete the below instructions to configure your settings.xml to use it. For more information about configuring a Maven repository manager, see Maven Repository Manager.

Before you build the source code, create a local Maven directory and update the settings.xml file.

1. Create an .m2 directory in your local user home directory. Example: mkdir ~/.m2

2. Copy the settings.xml file from the extensions/maven folder of the ep-commerce source code to your ~/.m2 folder.

3. Edit the following values in the settings.xml file to match your local developer environment.

   Setting	Description
   epdb.reset_user	Maven Profile: mysql-dev-db. The database account with administrative permissions that can drop and create databases and users in your local database.
   epdb.reset_password	Maven Profile: mysql-dev-db. The password for epdb.reset_user.
   ep.local.asset.path	The path to your local extensions/assets/ext-assets/src/main/assets source directory.
   ep.smtp.host	The host name of your SMTP Server.
   internet-mirror	The URL of your organization’s Nexus server. Verify that the URL is already set. If not, contact the person who set up the team environment. For more information, see Update Maven Settings.

   warning

   If these property values do not exist in the settings.xml file then you may have issues locally building and deploying the Self-Managed Commerce Web Applications.

Without A Maven Repository Manager

If your team has not yet prepared the Maven repository manager then complete the below instructions to configure your settings.xml to define the repositories locally. For more information about configuring a Maven repository manager see Maven Repository Manager.

The extensions module in Self-Managed Commerce source contains a maven/individual-settings.xml that you can use if your Maven repository manager is not yet ready.

1. Copy individual-settings.xml to ${user.home}/.m2 and rename it to settings.xml.

2. Change EP_REPOSITORY_USER and EP_REPOSITORY_PASSWORD to the credentials used for connecting to the public Elastic Path Maven repository.

   <servers>
       <server>
           <id>ep-public</id>
           <username>EP_REPOSITORY_USER</username>
           <password>EP_REPOSITORY_PASSWORD</password>
       </server>
       <server>
           <id>ep-cortex</id>
           <username>EP_REPOSITORY_USER</username>
           <password>EP_REPOSITORY_PASSWORD</password>
       </server>
       <server>
           <id>ep-commerce-engine</id>
           <username>EP_REPOSITORY_USER</username>
           <password>EP_REPOSITORY_PASSWORD</password>
       </server>
       <server>
           <id>ep-accelerators</id>
           <username>EP_REPOSITORY_USER</username>
           <password>EP_REPOSITORY_PASSWORD</password>
       </server>
   </servers>

3. Make any changes required for your project environment.

Local Database Setup

Self-Managed Commerce supports multiple database engines. Depending on which engine you choose, you will want to setup the corresponding database on your local development environment. Follow the steps in the appropriate section below.

MySQL

1. In a command prompt, run the shell command below to download and run the MySQL Docker image.

   For MySQL 8.0:

   docker run --name mysql-80-db --env="MYSQL_ROOT_PASSWORD=mysecretpassword" -p 3306:3306 -d mysql:8.0 --transaction_isolation=READ-COMMITTED --lower_case_table_names=1

   For MySQL 5.7:

   docker run --name mysql-57-db --env="MYSQL_ROOT_PASSWORD=mysecretpassword" -p 3306:3306 -d mysql:5.7 --transaction_isolation=READ-COMMITTED --lower_case_table_names=1

   note

   If you are using a Mac M1 or later, you will also need to add this parameter for MySQL 5.7: --platform=linux/amd64

   note

   It is recommended to change mysecretpassword to something more secure.

2. Edit your ~/.m2/settings.xml:

   1. In the <activeProfiles> section uncomment mysql-dev-db and comment out all other profiles ending with -dev-db.
   2. Check the mysql-dev-db profile definition and ensure that epdb.reset_password is set to the password you defined when starting the Docker image.

3. Browse to your Self-Managed Commerce repo, open folder extensions/database and run the following command: mvn clean install -Preset-db.

Oracle

If you are running on an M1 or M2 Macbook, follow the Install Oracle (M1/M2 Mac only) instructions. For all other operating systems, follow the Install Oracle (Non-M1/M2 Mac and Windows) instructions.

Install Oracle (M1/M2 Mac only)

1. Ensure that Docker is installed and running on your local machine.

5. Exit the Lima VM console.

   exit

PostgreSQL

A PostgreSQL database server can contain one or more named databases. Each database can contain one or more named schemas, which in turn contain tables. The Data Population tool will initialize a schema, but a database needs to be manually created first, using the instructions below.

1. In a command prompt, run the shell command below to download and run the PostgreSQL Docker image.

   docker run --name postgresql-16-db --env="POSTGRES_PASSWORD=mysecretpassword" -p 5432:5432 -d postgres:16 -c max_connections=1000

   note

   It is recommended to change mysecretpassword to something more secure.

2. Download and install pgAdmin.

3. Use following default credentials to connect to your PostgreSQL database from pgAdmin:

   • Username: postgres
   • Password: The password you defined when starting the Docker image.
   • Hostname: localhost
   • Port: 5432

4. Create a new database with name COMMERCEDB.

5. Edit your ~/.m2/settings.xml:

   1. In the <activeProfiles> section uncomment postgresql-dev-db and comment out all other profiles ending with -dev-db.

   2. Check the postgresql-dev-db profile definition and ensure that epdb.reset_user is set to postgres and epdb.reset_password is set to the password you defined when starting the Docker image.

   3. epdb.schemaname is set to public by default. This can be changed to any other value.

      note

      PostgreSQL converts schema name string to lowercase regardless of the value specified.

6. Browse to your Self-Managed Commerce repo, open folder extensions/database and run the following command: mvn clean install -Preset-db.
