maven - 「mvn パッケージ」を実行すると、一部のターゲットが 2 回実行されるのはなぜですか?

Question

完全な pom.xml ファイルは、ここで表示できます。件名が言うように、私が理解できないことが 1 つありmvn packageます。

なぜこれが起こるのですか？どうすればこれを回避できますか?

副次的な質問: リポジトリプラグインがインタラクティブにならないようにするにはどうすればよいですか?

まず、次のように maven-source-plugin の構成を変更する必要があります。

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-source-plugin</artifactId>
            <version>2.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>jar-no-fork</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

次に、maven-repository-plugin の実行をコメントアウトして、プラグインがライフサイクルを分岐させる必要があります。

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-repository-plugin</artifactId>
            <version>2.3.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>bundle-create</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

上記の 2 つのことを変更すると、default-compile などの重複実行が発生しなくなります。

maven - 「mvn パッケージ」を実行すると、一部のターゲットが 2 回実行されるのはなぜですか?
