因为Play framework 2.3以后采用SBT来构建项目,而SBT使用HTTPS从Maven服务器下载各种依赖包、资源和工具,导致构建过程非常慢。解决问题的思路是修改sbt配置,让Maven优先从阿里云镜像服务器中下载。
搭建步骤:
一、在IntelliJ Idea中安装Play 2.x和Scala插件
二、到Play framework官网下载Play的起始项目zip包。解压zip文件到文件目录假设是D:\sbt01312\
,顶层目录下有一个sbt-dist目录,里面包含sbt的launcher。
用winrar打开\bin\sbt-launch.jar
文件,把里面的\sbt\sbt.boot.properties
解压出来,然后在把[repositories]改为:
[repositories]
local
aliyun-maven: http://maven.aliyun.com/nexus/content/groups/public/
aliyun-ivy: http://maven.aliyun.com/nexus/content/groups/public/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
sbt-plugin-ivy: http://dl.bintray.com/sbt/sbt-plugin-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
dl-ivy: http://dl.bintray.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
store_mir:http://mirrors.ibiblio.org/maven2/
store_0:http://maven.net.cn/content/groups/public/
store_2:http://repo2.maven.org/maven2/
maven-central: http://repo1.maven.org/maven2/
typesafe-ivy-releases: https://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
sbt-ivy-snapshots: https://repo.scala-sbt.org/scalasbt/ivy-snapshots/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
把改好后的sbt.boot.properties放回\bin\sbt-launch.jar
文件。
三、运行IntelliJ Idea,选择File/Other Settings/Default Settings
菜单
在Build,Execution,Deployment/Build Tools/SBT页中,最下面的"Launcher(sbt-launch.jar)"中,选择Custom,然后输入框中输入第二步修改好的\bin\sbt-launch.jar
文件路径,例如D:\sbt01312\bin\sbt-launch.jar
四、在IntelliJ Idea中新建一个Play 2.x项目。
SBT会自动构建,并且下载各种文件,需要很长时间。执行到 Loading project definition from XXXXX 的时候会卡死。是因为项目根目录的build.sbt文件没有从镜像Maven中下载文件,而是从国外服务器下载。
此时可以终止构建,双击build.sbt打开文件,然后把最后的resolvers语句改为
resolvers += "aliyun-maven" at "http://maven.aliyun.com/nexus/content/groups/public/"
resolvers += Resolver.url("aliyun-ivy", url("http://maven.aliyun.com/nexus/content/groups/public/"))( Patterns("[organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]") )
resolvers += Resolver.url("sbt-plugin-ivy", url("http://dl.bintray.com/sbt/sbt-plugin-releases/"))( Patterns("[organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]") )
resolvers += Resolver.url("dl-ivy", url("http://dl.bintray.com/typesafe/ivy-releases/"))( Patterns("[organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]") )
注意:sbt文件两条语句之间要各一个空行,否则出错。
然后选择Run/Edit Configuration菜单,新建一个运行配置,然后运行这个配置。
如果顺利,项目会被重新构建,构建成功后启动浏览器进入项目页,此时配置就完全成功了。
