请帮忙,可能是什么原因? 预先感谢
编辑
好吧,当我删除时
<configuration>
<classpathScope>test</classpathScope>
<mainClass>ShiroDemo</mainClass>
</configuration>
来自 pom.xml 并使用以下命令执行它可以正常工作。 mvn 编译 exec:java -Dexec.mainClass="org.sample.test.ShiroDemo" -e
您不需要指定-Dexec.mainClass。您的配置正确,只是不在 pom.xml 中。将其更改为以下内容:
<mainClass>org.sample.test.ShiroDemo</mainClass>
