Conditional execution of maven plugin depending on profile property

Question

Given pom.xml

<plugin>
    <groupId>com.myplugin</groupId>
    <artifactId>my-plugin</artifactId>
    <version>1.0.0</version>
    <executions>
        <execution>
            <id>generate-file</id>
            <phase>package</phase>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <templateFile>
                    ${project.build.directory}/template.json
                </templateFile>
                <outputFile>
                    ${project.build.directory}/${env}-${server}-file.json
                </outputFile>
            </configuration>
        </execution>
        <execution>
            <id>send-file</id>
            <phase>package</phase>
            <goals>
                <goal>send</goal>
            </goals>
            <configuration>
                <file>
                    ${project.build.directory}/${env}-${server}-file.json
                </file>
            </configuration>
        </execution>
    </executions>
</plugin>

<profiles>
    <profile>
        <id>dev-a</id>
        <properties>
            <env>test</env>
            <server>serverA</server>
        </properties>
    </profile>
    <profile>
        <id>prod-a</id>
        <properties>
            <env>prod</env>
            <server>serverA</server>
        </properties>
    </profile>
    <profile>
        <id>dev-b</id>
        <properties>
            <env>test</env>
            <server>serverB</server>
        </properties>
    </profile>
    <profile>
        <id>prod-b</id>
        <properties>
            <env>prod</env>
            <server>serverB</server>
        </properties>
    </profile>
</profiles>

How can I execute send-file task only when env property is equal to prod? I know I can move the plugin tag to dev-a and prod-a profiles in that example but I would need to duplicate that part for each profile which doesn't seem to be good solution. In my case I have many more profiles defined and the plugin execution definition is much longer, it would clutter my pom file a lot and make any changes very error-prone. Is there any condition tag that I can pass to execution that would let me decide if it is invoked or not? Or maybe is there a possibility to exclude executions by id in profile tag?

Thanks for help!

Does this answer your question? [Using maven profiles to control build execution](https://stackoverflow.com/questions/4684837/using-maven-profiles-to-control-build-execution) — seenukarthi, Feb 19 '20 at 11:59
@KarthikeyanVaithilingam No, not really. They are describing an approach that I wanted to avoid as I reasoned in my question. I need to execute the same plugin for most profiles but not all, I don't want to just duplicate parts of file. — Please, Feb 19 '20 at 12:23
It looks like the plugin is not the right one to use...this should be handled by the plugin and not via profiles etc. — khmarbaise, Feb 19 '20 at 19:30

If my-plugin is really your plugin (i.e. you wrote it), the easiest thing would be to just implement the logic you want inside the plugin.

And what if it's not? Isn't there any way to disable execution of plugin with some property without adding such logic to plugin code? – Please Feb 20 '20 at 08:22
No nice ways, except for profiles. You can maybe set the skip property of the plugin by use of another plugin, conditionally. Let me also add a comment: It is usually not recommended to have different builds for different environments like dev, prod etc. Usually you use the very same artifact in all stages. – J Fabian Meier Feb 20 '20 at 08:39
