heroku(lift編)

Windows7+cygwinでherokuにliftを乗せる手順。

$ mvn -version
Apache Maven 3.0.3 (r1075438; 2011-03-01 02:31:09+0900)
Maven home: C:\Java\apache-maven-3.0.3
Java version: 1.6.0_26, vendor: Sun Microsystems Inc.
Java home: C:\Java32\jdk1.6.0_26\jre
Default locale: ja_JP, platform encoding: MS932
OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"

liftプロジェクト作成

$ mvn archetype:generate -DarchetypeRepository=http://scala-tools.org/repo-releases -DarchetypeGroupId=net.liftweb -
DarchetypeArtifactId=lift-archetype-blank_2.9.1 -DarchetypeVersion=2.4-M5

ビルド・実行

$ cd {projectのディレクトリ}
$ mvn package
$ mvn jetty:run

http://localhost:8080
で動作確認

C-cで止める

とりあえずgitに登録

# sbtのファイルは使わないので消してしまう
$ rm -rf project

$ echo target > .gitignore
$ git init
$ git add .
$ git commit -m "init"

war形式ではなくappassembler-maven-pluginを使うように変更する

ビルド

$ mvn package

実行

assebleしたjarを実行してみる

$ PORT=8080 ./target/bin/webapp

http://localhost:8080にアクセス。

C-cで止める

foreman

foreman化する

Procfile

web: sh target/bin/webapp

$ foreman start

http://localhost:5000にアクセス。

C-cで止める。

gitにコミット

$ git add Procfile
$ git add src/main/scala/RunWebApp.scala
$ git commit -a -m "fix for heroku"

herokuアプリ作成

$ heroku create --stack cedar

herokuデプロイ

$ git push heroku master

以上でheroku(lift編)終わり。
