java - Play Framework 构建不一致

Question

我第一次运行时得到以下堆栈跟踪激活器运行

[warn]  [NOT FOUND  ] org.apache.commons#commons-compress;1.7!commons-compress.jar (1ms)

有时我有机会按重试，当我这样做时它会成功。我正在用 docker 构建它，并希望它每次都能工作。

这是我的配置

build.sbt

name := """swsupplymonitor"""

version := "1.0-SNAPSHOT"

libraryDependencies ++= Seq(
  "mysql" % "mysql-connector-java" % "5.1.18",
  "com.typesafe.play" %% "anorm" % "2.4.0",
  "org.scalatest" %% "scalatest" % "2.2.1" % "test",
  "org.scalatestplus" %% "play" % "1.4.0" % "test",
  javaJdbc
)

lazy val root = (project in file(".")).enablePlugins(PlayScala)

build.properties

template.uuid=f5aa99a5-66e6-4ba6-abda-852c14da8938
sbt.version=0.13.8

plugins.sbt

logLevel := Level.Warn


// The Typesafe repository
resolvers += "Typesafe repository" at "https://repo.typesafe.com/typesafe/releases/"

// Use the Play sbt plugin for Play projects
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.8")

这是我的 Dockerfile

RUN mkdir /app

COPY ./ .

CMD ["activator", "run"]

我用这个命令运行

docker run -di -v $(pwd):/app:rw -p $PORT:9000 --name beacon-backend --link db:db beacon-backend

首先，检查您的连接。未解析的依赖项下载是因为在解析您的依赖项时 sbt 无法连接到远程存储库来下载它们。

如果您通过防火墙进行连接，请检查是否允许此 repo 协议(protocol)。
