Chapter 5. Configuring the Java compiler

Procedure

• To customize the compiler flags used in development mode, add a configuration section to the plugin block and set the compilerArgs property. You can also set source, target, and jvmArgs. For example, to pass --enable-preview to both the JVM and javac add the following lines:

  <plugin>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-maven-plugin</artifactId>
    <version>${quarkus-plugin.version}</version>
  
    <configuration>
      <source>${maven.compiler.source}</source>
      <target>${maven.compiler.target}</target>
      <compilerArgs>
        <arg>--enable-preview</arg>
      </compilerArgs>
      <jvmArgs>--enable-preview</jvmArgs>
    </configuration>
  
    ...
  </plugin>
