maven - Selenium Maven プラグイン実行時の Firefox プロファイルの「parent.lock」

Question

私の統合テストがmaven用のセレンプラグインで実行されるとき

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>selenium-maven-plugin</artifactId>
    <version>2.3</version>  
    <executions>
        <execution>
            <id>start</id>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>start-server</goal>
            </goals>
            <configuration>
                <background>true</background>
            </configuration>
        </execution>

        <execution>
            <id>stop</id>
            <phase>post-integration-test</phase>
            <goals>
                <goal>stop-server</goal>
            </goals>
        </execution>
    </executions>
</plugin>

次のメッセージが表示されます。

Lock file still present! C:\Users\ADM\AppData\Local\Temp\customProfileDirbb53fd86ecaf4236bf538b7a1171814b\parent.lock

firefox プロファイルが作成された直後に parent.lock ファイルを削除すると、テストは正しく機能します。parent.lock ファイルの作成を回避する方法を知っている人はいますか? または他の解決策

セレン2.33.0を使用しています

全体の例外は
