Maven-tomcat7-plugin产生损坏的可执行JAR

Question

我在使用Maven Tomcat7插件生成带有嵌入式Tomcat7实例的JAR存档时遇到问题。这是我的pom.xml片段：

        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <path>/${project.artifactId}</path>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>exec-war</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

我的项目使用war包装。生成了包含带有项目的WAR存档的Tomcat的JAR文件，但是当我尝试运行它时，出现错误：

我尝试了插件版本2.1-相同的结果。

这是通过执行JAR提取的目录树：

$ ls -AR .extract
.extract:
conf  logs  temp  webapps  work

.extract/conf:

.extract/logs:
access_log.2014-03-07

.extract/temp:

.extract/webapps:

.extract/work:
Tomcat

.extract/work/Tomcat:
localhost

.extract/work/Tomcat/localhost:
mailer

.extract/work/Tomcat/localhost/mailer:

（如您所见，没有文件被复制）

从配置中删除路径。并使用2.1版的tomcat插件。在pom文件中进行这两项更改对我来说解决了一个类似的问题。另外，$M2_REPO/org/apache在重新运行之前，我已经清理了文件夹。
