在做Spring MVC的应用时遇到一个奇怪的错误。具体如下：

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
<showWarnings>true</showWarnings>
</configuration>
</plugin>
<java.version>1.8</java.version>如果将java的编译版本修改成1.7。工程可以正常运行。
后来研究发现这是jetty插件的问题，将原来9.1.5.v20140505版本修改成0526版即可修复。
<plugin>
