Appending plugin more than once should add new execution to existing plugin in build section

[maxonfjvipon]

I want to use the same plugin on different phases. Here's the pom.xml I'd like to have:

<build>
  <plugins>
    <plugin>
      <groupId>org.eolang</groupId>
      <artifactId>eo-maven-plugin</artifactId>
      <executions>
        <execution>
          <phase>first</phase>
          <goals>
             ...
          </goals
        </execution>
        <execution>
          <phase>second</phase>
          <goals>
            ...
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

But by using Farea API like this:

f.build()
    .plugins()
    .append(
        "org.eolang",
        "eo-maven-plugin",
        System.getProperty("eo.version", "1.0-SNAPSHOT")
    )
    ...
f.build()
    .plugins()
    .append(
        "org.eolang",
        "eo-maven-plugin",
        System.getProperty("eo.version", "1.0-SNAPSHOT")
    )
    ...

I get 2 plugins instead of 2 executions which does not work because the second one rewrites the first one

<build>
  <plugins>
    <plugin>
      <groupId>org.eolang</groupId>
      <artifactId>eo-maven-plugin</artifactId>
      <executions>
        <execution>
          <phase>first</phase>
          <goals>
             ...
          </goals
        </execution>
      </executions>
    </plugin>
    <plugin>
      <groupId>org.eolang</groupId>
      <artifactId>eo-maven-plugin</artifactId>
      <executions>
        <execution>
          <phase>second</phase>
          <goals>
             ...
          </goals>
      </executions>
    </plugin>
  </plugins>
</build>
