jPatron BOM

• Easiest way to keep all jPatron artefacts of compatible versions is to include jpatron-bom in <dependencyManagement> section of your pom.xml
• When using BOM you don't have to specify version for every other jPatron artefact in <dependencies> section of your pom.xml, just specify it as <scope>provided</scope> and all jPatron dependencies will follow version of jpatron-bom artefact.

Maven (pom.xml)

<dependency>
    <groupId>info.nino.jpatron</groupId>
    <artifactId>jpatron-bom</artifactId>
    <version>${jpatron.version}</version>
    <scope>import</scope>
    <type>pom</type>
