git clone https://gitee.com/fastsource/flink
如何判斷當前版本是什麼型號呢？
看各種jar包的後綴名，如果是1.12就表示最新版本號是1.12了
flink-streaming-java_2.11-1.12-SNAPSHOT.jar
/home/appleyuchi/桌面/flink的配置實驗/flink/flink-runtime-web/pom.xml中
| 原來的 | 改成 |
| <arguments>ci --cache-max=0 --no-save</arguments> | install -g -registry=https://registry.npm.taobao.org --cache-max=0 --no-save |
終端運行:
$ npm config set registry http://registry.npm.taobao.org/
$ mvn clean install -T 2C -DskipTests -Dskip.npm -Dmaven.compile.fork=true
根據釘釘羣裏面的說法,flink編譯的時候是使用自帶的一個獨立的環境.
所以-Dskip.npm是用來防止本地nodejs/npm環境干擾的.
-T 2C的意思是機器開啓超線程工作.(我的電腦是四核八線程)
-Dmaven.compile.fork=true的意思是多核編譯.
到底是2C,1.5C還是1C在不同參考資料上有不通說法,下面進行實測，到底哪個快？
| 使用命令 | 耗時 |
| mvn clean install -T 1C -DskipTests -Dskip.npm -Dmaven.compile.fork=true | Total time: 15:54 min (Wall Clock) |
| mvn clean install -T 1.5C -DskipTests -Dskip.npm -Dmaven.compile.fork=true | Total time: 15:30 min (Wall Clock) |
| mvn clean install -T 2C -DskipTests -Dskip.npm -Dmaven.compile.fork=true | Total time: 13:52 min (Wall Clock) |
注意:
多核優勢只能在編譯部分(CPU密集)發揮，
並不能在下載依賴部分(CPU I/O)發揮
上述評測是基於之前第一次已經下載過依賴包,所以能大大節省依賴部分消耗的時間
Wall Clock的含義可以參考[1]
測試過程中可以看到CPU佔有率:
編譯後發現webui不能打開，JIRA上被告知是不能有Dskip.npm

根據[2]查詢v10.9.0對應的angular版本爲8.3.25
nvm install v10.9.0
切換到10.9.0版本
npm install -g @angular/[email protected]無法安裝core dumped
上面流程總共JIRA+釘釘騷擾了阿里四個人,總算是跑通了,反正騷擾一下總是可以的,恩.
