eclipse 中java/scala 混合的maven項目 工做環境篇

 

　　寫在前面：基本上靠java吃飯的吧,近兩年也有用到scala;但也沒有留下什麼痕跡,想起每次被問倒在基礎知識,那刻對方→_→ 懷疑的眼神~~。so right here, right now ! 今後沉澱下來。而後積沙成堆,積水成河 養成良好的習慣並鍥而不捨。p( ^ O ^ )q 加油！

 

　　1、IDE:scala-IDE(一直用這個),IntelliJ IDEA(耳聞),Netbeans(才知道)

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

　　3、建立項目的時候須要搜索、選擇插件,要增長URL：http://repo1.maven.org/maven2/archetype-catalog.xml

　　4、出現過mvn連不上公共庫的問題;

　　　　解決方法：eclipse.ini add : -vmargs -Djava.net.preferIPv4Stack=true

　　　　參考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項目步驟

　　　　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。

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

　　6、scala/java 項目mvn打包
