从事 java 开发工作两年, 对 java 的开发工具 IDEA 是最为满意, 编辑, 编译, UT\CT 全部本地搞定. 下面简单介绍 IDEA 的安装与使用.
Step 1: 官网下载 IDEA 软件安装包, 选择免费的开源版本, 手动安装;
Step 2: 下载 JDK
用 IDEA 创建 project, 要想完成编译必须下载 jDK, 并且安装, 如安装在以下目录 C:\Program Files\Java\jdk-11.0.1 在 IDEA configure 好, 可能遇到一系列问题.
- ERROR 1: Connect to repo.maven.apache.org:443
- [ERROR] Plugin org.springframework.boot:spring-boot-maven-plugin:1.5.4.RELEASE or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.springframework.boot:spring-boot-maven-plugin:jar:1.5.4.RELEASE: Could not transfer artifact org.springframework.boot:spring-boot-maven-plugin:pom:1.5.4.RELEASE from/to central (https://repo.maven.apache.org/maven2): Connect to repo.maven.apache.org:443 [repo.maven.apache.org/151.101.196.215] failed: Connection timed out: connect -> [Help 1]

修改 setting.xml 解决:
打开自己的 maven 的 setting 配置文件
根据 User setting file 提供的路径打开 setting.xml, 如果此文件不存在, 可以创建一个, 内容如下:
<?xml version="1.0" encoding="UTF-8"?> <settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/SETTINGS/1.0.0"> <proxies> <proxy> <id>optional</id> <active>true</active> <protocol>http</protocol> <username>proxyuser</username> <password>proxypass</password> <host>10.144.1.10</host> <port>8080</port> <nonProxyHosts>*.nokia.com</nonProxyHosts> </proxy> </proxies> <servers> <server> <id>deploymentRepo</id> <username>anonymous</username> <password>anonymous</password> </server> </servers> </settings>
加入如下节点, 保存;
<mirrors> <mirror> <id>osc</id> <mirrorOf>*</mirrorOf> <url>http://maven.oschina.net/content/groups/public/</url> </mirror> </mirrors>
然后 重新编译, 即可成功! 如果依旧没有成功, 把刚刚添加的 <mirrors > 节点内容全部删掉, 重新更新 maven 依赖, 然后重新编译, 这个问题就没有了.
ERROR 2: SDK 版本不匹配
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project FileSystem: Compilation failure: Compilation failure:
jdk-11.0.1 太新了, 卸载掉, 安装 jdk-8u92-Windows-x64.exe
根据下面提示的信息中重新设置 JDK
Maven 3.3.1+ requires JDK 1.7+. Please set appropriate JDK at Settings | Build, Execution, Deployment | Build Tools | Maven | Runner | JRE
ERROR 3:plugin 无法下载
设置代理, File->Settings->Plugins, 点击 Updates 右边的符号, 选择 Http Proxy Settings
ERROR 4: SNAPSHOT dependency 的错误

勾选 SE, 如下:
ERROR 5: SVN 下载失败
https://tortoisesvn.net/downloads.html
安装的时候注意勾选 command line
ERROR 6: CMake 问题
CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set http://www.cygwin.com/
下载安装 cygwin
