Description

I have one profile to configure maven-javadoc-plugin which is only activate for jdk 1.8 or greater. (doclint exist since java 1.8)
And another profile to use toolchain with jdk 1.7.

<profile>
    <id>configure-doclint</id>
    <activation>
        <jdk>[1.8,)</jdk>
    </activation>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-javadoc-plugin</artifactId>
                <configuration>
                    <doclint>all,-missing</doclint>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>
<profile>
    <id>useToolchain</id>
    <build>
        <plugins>
            <plugin>
                <artifactId>maven-toolchains-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>toolchain</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <toolchains>
                        <jdk>
                            <version>1.7</version>
                        </jdk>
                    </toolchains>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

The issue is that if I run  "mvn install javadoc:javadoc -PuseToolchain" with java 8 or greater, t}}his will failed with a "{{Exit code: 1 - javadoc: error - invalid flag: -Xdoclint:none"

I guess this is because jdk version which run maven is used instead of toolchain jdk version  to decide to activate or not "configure-doclint" profile.

Maybe it could make sense to add a new profile activation field <toolchain-jdk>.
If no toolchain is used the current running version of maven should be used and so in this case behave like <jdk>

WDYT ?
