Maven, war and scope = provided not working?

Question

Java

In general, there is a web project.
Assembled by maven.
In war.
I use a couple of libraries, but I need to use them with scope = provided, that is, do not include the library classes in the final war.
The problem is this: maven-war-plugin didn't care what I want there.
Still includes libraries in war.
If you switch the project to jar, everything is correct, you get a small jar.
Who knows how to convince this stubborn donkey?

I'm wildly sorry, I did mvn clean, everything is ok.
Damn, he couldn't have done it himself, could he?

You have an error somewhere. I just tried:

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>

and

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
            <scope>provided</scope>
        </dependency>

for

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.1.1</version>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
            </configuration>
        </plugin>

In the first case, I received jstl-1.2.jar in the .war archive, in the second - no.
Maybe you forgot to call mvn clean?
Or your library is included in transitive dependencies (although then, of course, it should also be included in the jar)
