Scala和Sbt配置

忘是亡心i 2023-07-06 04:50 4阅读 0赞

使用sbt，idea 创建 scala 工程，记录一下

1、安装sbt，配置使用其他镜像地址

windows 7 环境

下载地址：[https://www.scala-sbt.org/download.html][https_www.scala-sbt.org_download.html]

安装位置：D:\\sbt

（安装成功后，sbt运行环境地址，D:\\sbt\\bin，一般会自动添加到环境变量中）

如果不修改默认配置，使用默认镜像，则下载环境依赖的jar包，会很慢，基本是失败；

打开 D:\\sbt\\conf\\sbtconfig.txt，添加如下内容：

\-Dsbt.log.format=true  
\-Dsbt.boot.directory=D:/sbt/.sbt/boot  
\-Dsbt.ivy.home=D:/sbt/.ivy2  
\-Dsbt.global.base=D:/sbt/.sbt

\-Dsbt.repository.config=D:/sbt/conf/repository.properties

在D:\\sbt\\conf目录中，创建 repository.properties 文件，添加如下内容：

\[repositories\]  
local  
aliyun-nexus: http://maven.aliyun.com/nexus/content/groups/public/    
**ibiblio-maven: http://maven.ibiblio.org/maven2/**  
typesafe-ivy: https://dl.bintray.com/typesafe/ivy-releases/, \[organization\]/\[module\]/(scala\_\[scalaVersion\]/)(sbt\_\[sbtVersion\]/)\[revision\]/\[type\]s/\[artifact\](-\[classifier\]).\[ext\]  
**uk-repository: http://uk.maven.org/maven2/**  
jboss-repository: http://repository.jboss.org/nexus/content/groups/public/  
typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, \[organization\]/\[module\]/(scala\_\[scalaVersion\]/)(sbt\_\[sbtVersion\]/)\[revision\]/\[type\]s/\[artifact\](-\[classifier\]).\[ext\], bootOnly  
sonatype-oss-releases  
maven-central  
sonatype-oss-snapshots

【 还有aliyun的另外一个地址：

aliyun-nexus: http://maven.aliyun.com/nexus/content/repositories/central/

我在使用的过程中，发现环境依赖的包，多数是从ibiblio-maven，uk-repository中下载的       】

参考：[https://docs.scala-lang.org/getting-started-sbt-track/getting-started-with-scala-and-sbt-on-the-command-line.html][https_docs.scala-lang.org_getting-started-sbt-track_getting-started-with-scala-and-sbt-on-the-command-line.html]

创建scala工程目录，比如：F:\\scala

命令行进入，输入：sbt new scala/hello-world.g8

**第一次运行，会下载很多依赖包，需要等待较长时间；**

接着，下载工程模板，如下所示：

进入工程目录hello-world，输入：sbt         （会下载依赖的jar包）

输入：run    运行工程

2、IDEA，创建scala工程，使用独立安装的sbt环境；

首先安装idea scala插件；

参考：[https://docs.scala-lang.org/getting-started-intellij-track/building-a-scala-project-with-intellij-and-sbt.html][https_docs.scala-lang.org_getting-started-intellij-track_building-a-scala-project-with-intellij-and-sbt.html]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lodHBwcA_size_16_color_FFFFFF_t_70 3][]

配置，使用1步骤中，已经安装的sbt环境；

*  但是可能是版本原因,配置的本地仓库并没有生效,jar还是下载到了C盘，在查找资料后，发现还有另一个地方需要配置。

D:\\javaTool\\sbt\\bin\\sbt-launch.jar

配置文件是在D:\\javaTool\\sbt\\bin\\sbt-launch.jar中的\\sbt\\sbt.boot.properties中（可用rar解压工具直接打开修改并覆盖，记住是用rar打开文件不需要解压，否则弄不回jar了），修改里面的内容：

[scala]
      version: ${sbt.scala.version-auto}
    
    [app]
      org: ${sbt.organization-org.scala-sbt}
      name: sbt
