Can't generate neither javadoc nor sources via maven-plugins?

Question

I want to generate javadoc from my code in Intellij idea IDE.
I'm going step by step by This link. but I don't get the appropriate result.

But after doing mvn package there was no neither attach-source-javadoc-1.0-SNAPSHOT-javadoc.jar nor attach-source-javadoc-1.0-SNAPSHOT-sources.jar files under target folder.

This is the whole pom file:

  <?xml version="1.0" encoding="UTF-8"?>

Answer 1

You have added the plugin to the <pluginManagement> which is not executed.

To generate both javadoc and source code via maven-plugins
You have to put this inside <plugins>directly:

<build>
    <plugins>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-source-plugin</artifactId>
            <executions>
                <execution>
                    <id>attach-sources</id>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-javadoc-plugin</artifactId>
            <executions>
                <execution>
                    <id>attach-javadocs</id>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <failOnError>false</failOnError>
            </configuration>
        </plugin>

    </plugins>
</build>
