try中定义输入流报错:Try-with-resources are not supported at language level '5'
报错现象:
处理过程:
1、先是查看了Project Structure,发现设置的都是1.8
2、然后又查看了Settings->Build,Execution,Deployment->Compiler->Java Compiler,发现设置的也是8
3、修改pom文件,在project下添加如下配置,问题解决:
<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>8</source> <target>8</target> </configuration> </plugin> </plugins> </build>
