However, it’s easy to mix configuration and execution time states when writing dynamic tasks. You can also see that 'inputs' are untyped in dynamic tasks, which can lead to issues. When you implement your custom task as a class, you can clearly define the inputs as properties with a dedicated type.</p> </div> <div class="paragraph"> <p>Dynamic modification of task actions can provide value for tasks that are already registered, but which you need to modify for some reason.</p> </div> <div class="paragraph"> <p>Let’s take the <code>compileJava</code> task as an example.</p> </div> <div class="paragraph"> <p>Once the task is registered, you can’t remove it.
