# 1. 问题 #

# 2.原因 #

真正的原因是，模块目标 jdk 版本与 IDE 不相同。

# 3. 解决方法 #

**检查项目的java编译版本号**  
Preferences->Build,Execution,Deployment->Compiler->Java Compiler->Javac Options

修改版本号  
![在这里插入图片描述][5aba1d0f2fe74410bc99d46e029f644d.png]  
**pom.xml文件修改**

<?xml version="1.0" encoding="UTF-8"?>
    <project>
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <maven.compiler.source>1.8</maven.compiler.source>
            <maven.compiler.target>1.8</maven.compiler.target>
        </properties>
    </project>

或者修改

<project>
    ...
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.6.1</version>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </project>
