<profiles>
        <profile>
            <id>my-json-test</id>
            <activation>
                <file>
                    <exists>/foo/test.json</exists>
                </file>

Say the file /foo/test.json dosn't exixst .. how this activation can print error ? as now it do not print any thing just fail the build task .

It looks like you are using profiles for the wrong reason. As I read it you want to enforce that this file exists. As with anything you want to enforce, the maven-enforcer-plugin is your friend. In this case try https://maven.apache.org/enforcer/enforcer-rules/requireFilesExist.html
