maven pass -xlint:all to compiler

[Gerard Gauthier]

I can't get the maven's compile phase to display the warning below(Note: If I compile with javac -Xlint:all [path to NothingHere file] then I get the warning).

warning: [serial] serializable class NothingHere has no definition of serialVersionUID
final public class NothingHere extends Exception {

I tried updating the pom.xml with
...  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <maven.compiler.source>10</maven.compiler.source>    <maven.compiler.target>10</maven.compiler.target>  </properties> ...  <build>    <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->      <plugins>        <!-- clean lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#clean_Lifecycle -->        <plugin>          <artifactId>maven-compiler-plugin</artifactId>          <version>3.8.0</version>          <configuration>            <compilerArgs>              <arg>-Xlint:all</arg>            </compilerArgs>          </configuration>        </plugin>        <plugin> ...

But when I call mvn compile or package I get no warning message.. Any pointers?

Also: I'm using maven's quickstart.

Maven disables compiler warnings by default. This is the configuration you need:
         <configuration>            <compilerArgs>              <arg>-Xlint</arg>            </compilerArgs>            <showWarnings>true</showWarnings>          </configuration>

Thanks Stephan.. That worked!
