Linux环境下配置Eclipse和Maven

1、下载Eclipse：

http://mirrors.ustc.edu.cn/eclipse/technology/epp/downloads/release/oxygen/3a/eclipse-jee-oxygen-3a-linux-gtk-x86_64.tar.gz

2、下载Maven：

http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.5.3/binaries/apache-maven-3.5.3-bin.tar.gz

3、在opt目录下创建文件夹tools

4、解压Maven

[root@master java]# tar -zxf /opt/software/apache-maven-3.5.3-bin.tar.gz -C /opt/java/

5、配置Maven的环境变量：vi /etc/profile

6、验证是否配置成功：

7、解压Eclipse到tools目录

[root@master ~]# tar -zxf /opt/software/eclipse-jee-oxygen-3a-linux-gtk-x86_64.tar.gz -C /opt/tools/

8、启动Eclipse（要在虚拟机的页面启动）

发现了如下的报错：（我的虚拟机是CentOS 6.4）

9、无奈，用更早版本的Eclipse吧

eclipse-jee-kepler-SR1-linux-gtk-x86_64.tar.gz

10、设置workspace

11、配置Maven：Window -->Preferences-->Maven-->Installations

如下图，选择Maven的存放路径

12、重新进入，选择Window -->Preferences-->Maven-->User Settings

发现User settings file doesnt exist。创建底下两个路径

将Maven目录下的settings.xml 拷贝过来：

[root@master .m2]# cp /opt/java/apache-maven-3.5.3/conf/settings.xml .

13、创建Maven Project

14、创建好后，就开始各种下载，下载后Project的目录如下

15、发现报错咯，报错内容如下：

org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project.MavenProject, org.apache.maven.archiver.MavenArchiveConfiguration)

参考：https://blog..net/m0_37355951/article/details/72954015

16、执行以上步骤后，终于看到喜欢看到的页面啦

17、创建sources路径

18、设置source的输出路径：

最后选择如图：

19、配置pom.xml
