Update Jenkins version

Require a newer minimum Jenkins version

Jenkins plugins declare a minimum supported Jenkins version. The minimum Jenkins version is a good way for plugin developers to indicate the range of Jenkins versions they are willing to support and test. See the developer documentation for the recommended minimum Jenkins version.

Create a branch

In a local copy of your fork of the plugin repository create a git branch for your work with the command:

git checkout -b require-newer-core master

Update minimum required Jenkins version

Update the minimum required Jenkins version by setting a jenkins.version value in the properties section of the pom.xml file:

   <properties>
     <jenkins.version>2.452.4</jenkins.version>
   </properties>

If the plugin is already using the plugin bill of materials, then the bill of materials also needs to be updated with the matching artifactId for the minimum required Jenkins version. The version may also need an upgrade see the developer documentation.

The git diff might look like this:

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>io.jenkins.tools.bom</groupId>
-        <artifactId>bom-2.375.x</artifactId>
+        <artifactId>bom-2.440.x</artifactId>
-        <version>2198.v39c76fc308ca</version>
+        <version>3435.v238d66a_043fb_</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

Compile the plugin

Use Apache Maven to compile the plugin and run its automated tests with the command:

mvn clean verify
