如何从Play中删除所有默认解析器!应用？

Question

背景:我们公司有几个Play!应用程序,它们的测试在我们的内部CI中运行.每个Play应用程序都通过http检索各种公共存储库的依赖关系.这不是理想的(它绕过我们的内部Nexus存储库)但可以忍受.现在我们正在添加额外的CI容量,并且不希望允许新计算机能够访问防火墙外部.

在示例Play应用程序中,以下配置project/Build.scala不足以阻止构建进入repo.typesafe.com和repo1.maven.org:

sbtResolver := "Typesafe (proxy)" at "http://repo-1/nexus/content/repositories/typesafe-releases/"

resolvers := Seq(
  "Maven Central (proxy)" at "http://repo-1/nexus/content/repositories/central/",
  "Typesafe (proxy)" at "http://repo-1/nexus/content/repositories/typesafe-releases/",
  // some more internal Nexus repositories
)

externalResolvers := Seq.empty

(repo-1是我们的内部Nexus主机,代理Maven Central,Typesafe和其他存储库)

当我无论是从中央Maven的(如番石榴)或从类型安全的存储库(如播放邮件插件)中删除一些依赖,并运行play compile,我从仍被从检索到的依赖性输出看到的repo.typesafe.com和repo1.maven.org:

[info] downloading http://repo.typesafe.com/typesafe/releases/com/typesafe/play-plugins-mailer_2.9.1/2.0.2/play-plugins-mailer_2.9.1-2.0.2.jar ...
[info]  [SUCCESSFUL ] com.typesafe#play-plugins-mailer_2.9.1;2.0.2!play-plugins-mailer_2.9.1.jar (981ms)
[info] downloading http://repo1.maven.org/maven2/com/google/guava/guava/12.0/guava-12.0.jar ...
[info]  [SUCCESSFUL ] com.google.guava#guava;12.0!guava.jar (1422ms)

为了解决这个问题,我们还提供了一些稍微旧版本的东西:Scala 2.9.1,Play 2.0.1,sbt 0.11.3.

如何强制Play应用程序专门从内部存储库中检索依赖项？

Answer 1

原来答案是使用正确的sbt语法.

问题中列出的代码是为构建生成配置,但不在任何地方分配它.我相信:=替换了resolvers密钥的全局配置,但事实并非如此.

把下面的project/Build.scala强制播放应用从我们内部的Nexus解决依赖关系:

val nexusResolvers = resolvers := Seq(
  "Maven Central (proxy)" at "http://repo-1/nexus/content/repositories/central/",
  "Typesafe (proxy)" at "http://repo-1/nexus/content/repositories/typesafe-releases/",
  // some more internal Nexus repositories
)

请注意将结果分配给resolvers :=新的val,然后将其添加到同一文件中的项目设置中:

val main = PlayProject(...)
  .settings(nexusResolvers: _*)

而且,摆脱了中sbtResolver和externalResolvers的配置,这是没有效果的部分.

Answer 2

编辑或创建 /home/YOUR_HOME/.sbt/repositories 添加以下内容：

[repositories] local my-maven-proxy-releases: http://nexus_domain_or_ip:8081/nexus/content/groups/public/

运行play时添加此参数：-Dsbt.override.build.repos=true

例如：激活器运行-Dsbt.override.build.repos=true

这可以防止游戏加载项目配置中定义的存储库。
