# 一、IDEA #

## 1、Project SDK 和 Project language level ##

*  有关Project SDK 和 Project language level 的说明可以参见：  
    [idea language level 介绍][idea language level]

## 2、Module SDK 和 Project language level ##

说明：Module SDK 和 Project language level 默认同于Project。也可以单独设置每个Module。

## 3、Java Compiler ##

# 二、Maven项目 #

两种方式

## 1、POM properties ##

<maven.compiler.source>1.8</maven.compiler.source>
     <maven.compiler.target>1.8</maven.compiler.target>

## 2、maven-compiler-plugin ##

前提：得用maven进行compile

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
    <configuration>
      <source>1.8</source>
      <target>1.8</target>
    </configuration>
    </plugin>

参见官方说明：[Setting the -source and -target of the Java Compiler][]

# 三、Gradle项目 #

build.gradle中设置：

sourceCompatibility = 1.8
    targetCompatibility = 1.8
