# 一、问题回顾 #

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70][]

Version 1.7.0\_79 of the JVM is not suitable for this product.Version:1.8 or greater is required.

大概的意思就是 jdk1.7 不能满足eclipse的运行，需要安装 jdk1.8 及以上的版本才可以。Windows+R 输入 cmd 打开命令行提示符，输入java -version 查看 jdk 版本，确实是 1.7 的，那么接下来就安装 1.8 的来解决一下问题。

# 二、登录官网下载 #

**1、浏览器打开 [https://www.oracle.com/index.html][https_www.oracle.com_index.html]**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 1][]

**2、点击左上角的更多图标，找到 Downloads，点击进去**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 2][]

**3、下滑页面，找到 Java，点击进入；**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 3][]

**4、点击 Java（JDK）for Developers；**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 4][]

最新版本是 JDK1.13 的，一般选择旧版本，因为旧版本比较稳定。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 5][]

**5、拖到最下面，找到 Java Archive，点击DOWLOAD进去就可以看到旧版本了。**

我要下载1.8的，选择其中一个点击即可；

**6、进入后勾选同意规则后，便可点击 jdk-8u231-windows-x64.exe 进行下载，下载需要登录，没账号自己注册一个就好了。**

# 三、安装配置 #

**1、安装**

下载后找到安装路径，直接点开就是安装向导，一直下一步就可以了，其间可以看个人需求更改安装路径。

![20200121122038466.png][]

**2、环境配置**

（1）在【此电脑】右键打开属性

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 9][]

（2）点击【高级系统设置】

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 10][]

（3）点击【环境变量】

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 11][]

（4）在系统变量区域，点击新建。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 12][]

（5）变量名：JAVA\_HOME ，变量值为 jdk 的安装路径。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 13][]

（6）新建变量名：CLASSPATH ，变量值： .;%JAVA\_HOME%\\lib\\dt.jar;%JAVA\_HOME%\\lib\\tools.jar

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 14][]

（7）找到Path变量，双击编辑 Path变量。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 15][]

（8）点击新建，变量值为%JAVA\_HOME%\\bin ，并将它移到最前端，然后点击确定。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 16][]

**3、检验配置**

1、Windows+R 输入 cmd 打开命令行提示符，输入java -version 后回车

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 17][]

2、再输入**javac.exe**命令。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 18][]

这样 jdk1.8 的安装和配置就完成了。

# 四、修改配置文件 #

打开eclipse的安装目录，找到 eclipse.ini 文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 19][]

编辑修改，将1.7的那个删掉，换成1.8的保存。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 20][]

再次打开eclipse，噗，又报错了

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 21][]

检查一下是高级配置的时候出问题了，改正过来就可以打开了。
