Please show the command you have used... not only the error output... — khmarbaise, Mar 02 '21 at 15:01
How's your pipeline like? If you build your project locally, how's the result? — Cece Dong - MSFT, Mar 03 '21 at 07:13

You may try to use a plugin directly in the pom, for example:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <testSource>1.8</testSource>
                <testTarget>1.8</testTarget>
                <compilerArgument>-Xlint:deprecation</compilerArgument>
            </configuration>
        </plugin>
    </plugins>
</build>

This might due to maven download problem so I have clean up the .m2 repository on Jenkins slave and the plug in then was downloaded again .It worked for me & no code change required .
