sbt - 如何仅在 Travis 和 sbt 0.13 下的 master 分支上发布

Question

我正在使用 Travis 进行持续构建和集成。

after_success:
- sbt publish

虽然我们希望 Travis 构建我们所有的分支和拉取请求，但我们只希望它 publish何时开启 master分支。

publishTo <<= version { (v: String) =>
  val nexus = s"asdf"
  /* Don't let Travis publish when building pull requests.
   * $TRAVIS_PULL_REQUEST == "false" if it's not a pull request.  So we wan't publishTo to be
   * None when TRAVIS_PULL_REQUEST != false.
   */
  if(Try(sys.env("TRAVIS_PULL_REQUEST")).getOrElse("false") != "false")
    None
  /* Don't let Travis publish except when building master. */
  if(Try(sys.env("TRAVIS_BRANCH")).map(_ != "master").getOrElse(false))
    None
  else if(v.trim.endsWith("SNAPSHOT"))
    Some("snapshots" at nexus + "snapshots")
  // don't let Travis publish releases, either
  else if(Try(sys.env("TRAVIS")).getOrElse("false") == "true")
    None
  else
    Some("releases"  at nexus + "releases")
})

这种方法的问题在于 Travis 编译分支两次，因为它在最后一步发布失败。

如何完全阻止 Travis 运行 sbt publish当在非 master分支？

您可能会考虑在发布脚本之外处理此问题:

after_success:
  - test $TRAVIS_PULL_REQUEST == "false" && test $TRAVIS_BRANCH == "master" && sbt publish
