Sort plugins by executionId

So that the gpg plugin can be sorted after javadoc and source plugin

Sorted plugins should keep this order ’ <sortPlugins>executionId,groupId,artifactId</sortPlugins>’

          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-javadoc-plugin</artifactId>
            <version>3.2.0</version>
            <configuration>
              <minmemory>128m</minmemory>
              <maxmemory>512</maxmemory>
              <breakiterator>true</breakiterator>
              <quiet>true</quiet>
              <source>${compileSource}</source>
              <verbose>false</verbose>
              <linksource>true</linksource>
              <links>
                <!-- JSE -->

            </configuration>
            <executions>
              <execution>
                <id>1_attach-javadoc</id>
                <goals>
                  <goal>jar</goal>
                </goals>
                <phase>verify</phase>
              </execution>
            </executions>
          </plugin>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-source-plugin</artifactId>
            <version>3.2.1</version>
            <executions>
              <execution>

                <goals>
                  <goal>jar-no-fork</goal>
                </goals>
                <phase>verify</phase>
              </execution>
            </executions>
          </plugin>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-gpg-plugin</artifactId>
            <version>1.6</version>
            <executions>
              <execution>
                <id>3_sign-artifacts</id>
                <goals>
                  <goal>sign</goal>
                </goals>
                <phase>verify</phase>
              </execution>
            </executions>
          </plugin>

YMMV, but I usually sort after the phase and my ids don’t have numbers (I have actually never seens executionIds starting with numbers). Just my 2 cents.

The problem with phases is that the plugin does not analyze the content of the POM. It is basically an xml sorter with custom xml ordering. So the plugin does not know about a default phase of a plugin unless you explicitly state each phase in the pom file. I agree that sorting by phase would be excellent, but that is a job for another plugin.
