eclipse 中java/scala 混合的maven项目 工做环境篇

 

　　写在前面：基本上靠java吃饭的吧,近两年也有用到scala;但也没有留下什么痕迹,想起每次被问倒在基础知识,那刻对方→_→ 怀疑的眼神~~。so right here, right now ! 今后沉淀下来。而后积沙成堆,积水成河 养成良好的习惯并锲而不舍。p( ^ O ^ )q 加油！

 

　　1、IDE:scala-IDE(一直用这个),IntelliJ IDEA(耳闻),Netbeans(才知道)

　　2、安装m2eclipse-scala插件,URL：http://alchim31.free.fr/m2e-scala/update-site/

　　3、建立项目的时候须要搜索、选择插件,要增长URL：http://repo1.maven.org/maven2/archetype-catalog.xml

　　4、出现过mvn连不上公共库的问题;

　　　　解决方法：eclipse.ini add : -vmargs -Djava.net.preferIPv4Stack=true

　　　　参考https://www.eclipse.org/forums/index.php/t/270718/(Starting Eclipse with -vmargs -Djava.net.preferIPv4Stack=true works for me)

　　5、建立支持scala的mvn项目步骤

　　　　Select New -> Project -> Other and then select Maven Project. On the next window, search forscala-archetype. Make sure you select the one in group net.alchim31.maven, and click Next。

　　　　参考http://scala-ide.org/docs/tutorials/m2eclipse/index.html#create-a-new-scala-maven-project

　　6、scala/java 项目mvn打包
