我正在使用 maven 构建部署在 tomcat 服务器上的项目。构建过程成功完成,但是当我尝试在 tomcat 7 上部署项目时,它抛出错误。我可以看到 twelemonkey-servlet.jar 存在于 WEB-INF 的 lib 文件夹中。
pom.xml
<repository>
<id>project.local</id>
<name>project</name>
<url>file://${project.basedir}/repo</url>
</repository>
<dependency>
<groupId>com.twelvemonkeys.imageio</groupId>
<artifactId>imageio-metadata</artifactId>
<version>3.06</version>
</dependency>
<dependency>
<groupId>com.twelvemonkeys</groupId>
<artifactId>twelvemonkeys-servlet</artifactId>
<version>3.08</version>
</dependency>
构建成功,但是在部署时我遇到了以下异常
