用maven自定義spark任務的archetype
阿新 • • 發佈:2019-02-17
本來spark工程是推薦用sbt的,但是sbt因為某些原因在國內實在是太慢了,所以嘗試用eclipse+maven+scala外掛,
然而scala-tools提供的archetype預設使用scala2.7.0,讓人每次都去修改,然後又要去新增Hadoop、spark之類的依賴,有時候還出現包衝突
,有時候一不小心忘了,編譯的時候還會出錯。 於是我決定生成一個自己用的archetype,以圖省事。
以下流程需要使用自己安裝的maven,使用eclipse自帶的maven會報錯。
可以從Window->Preferences->Maven->Installations裡面add自己maven的安裝目錄。
1、建立一個maven工程,最好用scala的archetype,因為在上面修改起來方便,隨便取個名字,比如spark-archetype 2、把自己想要的目錄下面隨便建個檔案,這一點是為了讓得到的archetype會自動生成資料夾,如果有不用建個檔案就保留資料夾的 方法,請務必聯絡我
4、右鍵該pom.xml檔案,run as->maven build... 輸入archetype:create-from-project,完成後,target下面會生成generated_sources資料夾,下面會有一個 名字叫archetype的工程。 此步驟也可以在cmd中cd到工程目錄下,使用 mvn archetype:create-from-project命令 5、右鍵4中生成的archetype工程下面的pom.xml檔案,即target/generated_sources/archetype/pom.xml檔案,run as->maven build... 輸入install,該archetype 就會安裝到本地的maven庫中,也可以在cmd中cd到archetype目錄下面,使用mvn install命令 然後通過file->new ->other...->Maven Project,後面選擇archetype的時候,catalog選擇Default Local,會出現剛才安裝的archetype:

3、編輯pom.xml,新增常用的依賴,比如spark、Hadoop、hbase,等等。 可以把version用變數的方式提到前面,方便修改。像這樣:
然後在build裡面新增archetype外掛:</pre><pre name="code" class="html"> <properties> <scala.version>2.10.4</scala.version> <spark.version>1.4.1</spark.version> <hadoop.version>2.2.0</hadoop.version> </properties>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-archetype-plugin</artifactId>
<version>2.2</version>
</plugin>
完整的pom.xml檔案會放在文後。4、右鍵該pom.xml檔案,run as->maven build... 輸入archetype:create-from-project,完成後,target下面會生成generated_sources資料夾,下面會有一個 名字叫archetype的工程。 此步驟也可以在cmd中cd到工程目錄下,使用 mvn archetype:create-from-project命令 5、右鍵4中生成的archetype工程下面的pom.xml檔案,即target/generated_sources/archetype/pom.xml檔案,run as->maven build... 輸入install,該archetype 就會安裝到本地的maven庫中,也可以在cmd中cd到archetype目錄下面,使用mvn install命令 然後通過file->new ->other...->Maven Project,後面選擇archetype的時候,catalog選擇Default Local,會出現剛才安裝的archetype:
