我正嘗試在SBT Native Packager的幫助下創建帶有不同配置文件的構建。我有斯卡拉項目標準的項目佈局:SBT Native Packager:使用不同的配置構建相同的包
my-app

----/plugins.sbt

build.sbt
所以我加了SBT-本機打包插件到我的項目,並決定重複SBT submodule approach。
這就是我的build.sbt文件看起來像:
import sbt.Keys._
scalaVersion in ThisBuild := "2.12.1"
lazy val app = project
.in(file("."))
.settings(
name := "backend",
version := "1.0",
libraryDependencies ++= {
val akkaVersion = "2.4.17"
val akkaHttpVersion = "10.0.5"
Seq(
"com.typesafe.akka" %% "akka-actor" % akkaVersion,
"com.typesafe.akka" %% "akka-http" % akkaHttpVersion,
"com.typesafe.akka" %% "akka-http-spray-json" % akkaHttpVersion
)
}
)
lazy val devPackage = project
.in(file("build/dev"))
.enablePlugins(JavaAppPackaging)
.settings(
name := "backend-dev",
resourceDirectory in Compile := (resourceDirectory in (app, Compile)).value,
mappings in Universal += {
((resourceDirectory in Compile).value/"dev.conf") -> "conf/application.conf"
}
)
.dependsOn(app)
這裏是application.conf和dev.conf(均放在src /主/資源:
akka {
loglevel = INFO
stdout-loglevel = INFO
loggers = ["akka.event.slf4j.Slf4jLogger"]
default-dispatcher {
fork-join-executor {
parallelism-min = 8
}
}
http {
server {
server-header = "PinPoint REST API"
request-timeout = "10.seconds"
}
}
}
database {
dataSourceClass = "org.postgresql.ds.PGSimpleDataSource"
properties = {
databaseName = "pg_db"
user = "alex"
password = ""
}
numThreads = 10
}
和
include "application"
database {
dataSourceClass = "org.postgresql.ds.PGSimpleDataSource"
properties = {
databaseName = "pg_db_dev"
user = "alex"
password = "secure_password"
}
numThreads = 10
}
我運行在終端sbt devPackage/stage
後,我得到了根folde新目錄「打造」該項目的r。但在裏面: build/dev/target/universal/stage/ 沒有帶可運行sh腳本的「bin」文件夾。
那麼如何解決這個問題呢?
如果你有不同的主類,那麼你需要指定其中一個像mainClass在編譯:=一些(「foo.bar 。主要」)。有關更多詳細信息,請參閱http://www.scala-sbt.org/sbt-native-packager/archetypes/java_app/。 – kardapoltsev
@kardapoltsev我只有一個主類 –
