Create and set up Maven projects

Create a Java project called "Activity Developer QuickStart" (hereinafter referred to as $quickStart Java Project Name), which contains the following Maven dependencies:

Document: $mvnProject/pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>$quickStartJavaProjectName</groupId>
  <artifactId>$quickStartJavaProjectName</artifactId>
  <version>0.0.1-SNAPSHOT</version>

  <!-- ... other configurations may exist, such as a build stanza, depending your environment ... -->

  <dependencies>
    <dependency>
      <groupId>org.activiti</groupId>
      <artifactId>activiti-engine</artifactId>
      <version>$actVer</version>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>1.7.21</version>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-log4j12</artifactId>
      <version>1.7.21</version>
    </dependency>
    <dependency>
      <groupId>com.h2database</groupId>
      <artifactId>h2</artifactId>
      <version>1.4.193</version>
    </dependency>
  </dependencies>
</project>

Of course, $actVer will be replaced with the downloaded Activiti version. For example, if the Activiti package you downloaded is "Actiti-5.22.0", then the value of $actVer will be 5.22.0.

Note the following dependencies:

• Activiti (org.activiti) - BPM engine of Activiti
• Database (com.h2database) - H2 database
• Logging (org.slf4j) - Simple Logging Appearance for Java

When referring to the build directory, this tutorial assumes the standard Maven build path for your maven project:

You should be able to build a blank project. Before continuing, make sure that the overall status is "BUILD SUCCESS".

Command: mvn compile

Base path: $mvnProject

Your output may look different, and most notably, maven may need to retrieve project dependencies.
