How to avoid/resolve this warning? P/S: Comment about not dupplicated question. In this question and solution https://stackoverflow.com/a/74601911/3728901 , use maven-compiler-plugin , not spring-boot-maven-plugin .

Answer 1

I'm using spring-context version 6.0.11 and the problem still exists.

SHORT ANSWER:

Add this build plugin to the pom.xml file of your project:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <compilerArgs>
                    <arg>-parameters</arg>
                </compilerArgs>
            </configuration>
        </plugin>
    </plugins>
</build>

If you already have this plugin in your pom.xml file then just add configuration part to the existing Maven compiler plugin:

<configuration>
    <compilerArgs>
        <arg>-parameters</arg>
    </compilerArgs>
</configuration>

MORE DETAILED ANSWER:

Apache Maven Compiler Plugin is used to compile the sources of your Maven project.

When you specify this plugin in your project you can add configuration to it:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        ...
    </configuration>
</plugin>

For example, if you want to use the Java 8 language features (-source 1.8) and also want the compiled classes to be compatible with JVM 1.8 (-target 1.8), you can either add the two following configuration:

<configuration>
    <source>1.8</source>
    <target>1.8</target>
</configuration>

Another configuration we can specify is passing arguments to the Java compiler (javac):

<configuration>
    <compilerArgs>
        <arg>-parameters</arg>
    </compilerArgs>
</configuration>

We passed -parameters as an additional argument to the compiler. And of course both preceding configurations can be used together.

Answer 2

This is a known bug and there is a Spring Issue for it. But it is not harmful and you do not need to take any action unless you just don't want warnings in your logs.

From the issue:

It looks like the core bean factory is unnecessarily retrieving constructor parameter names during the constructor autowiring algorithm, despite no constructor argument names having been specified. That's a bug we're going to fix in [Spring Framework] 6.0.3."

and

For the time being, you may simply disable the warn log category for org.springframework.core.LocalVariableTableParameterNameDiscoverer. There is unnecessary reading of class files in the meantime but otherwise no harm for your application.
