Extending java.base in a project built with Maven

Maven 3.9.0 invalid flag --patch-module is what I get when I run mvn clean compile on my project that extends java.lang package. When I run javac --patch-module java.base=src <path-to-source> all is good.

The reason is - Maven uses com.sun.tools.javac.api.JavacTool which when parsing <compilerArgs> is using only the BASIC Option group and --patch-module is in the FILEMANAGER group. This raises an illegal flag exception during mvn clean compile.

Does anyone know how I can get it to work with Maven? I'd prefer not to make my CI pipeline using javac command line tool.

Project structure is like:
src -> main -> java -> java.lang -> <classes>

pom.xml looks like:

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.10.1</version>
                <configuration>
                    <source>${java.source.sdk}</source>
                    <target>${java.source.sdk}</target>
                    <compilerArgs>
                        <arg>--patch-module java.base=src</arg>
                    </compilerArgs>
                </configuration>
            </plugin>
        </plugins>

Maven version:

Maven home: /opt/homebrew/Cellar/maven/3.9.0/libexec
Java version: 18, vendor: Oracle Corporation, runtime: /Users/<username>/Library/Java/JavaVirtualMachines/openjdk-18/Contents/Home
Default locale: en_RS, platform encoding: UTF-8
OS name: "mac os x", version: "12.6.2", arch: "aarch64", family: "mac"

Used JDK 19 -> same result. Used Maven 3.10.1 -> same result.

Maven parses the argument as one long argument with embedded whitespace.

This is what it is supposed to look like:

<compilerArgs>
    <arg>--patch-module</arg>
    <arg>java.base=src</arg>
</compilerArgs>

See the Maven documentation for example.
