# Publish maven project to JCenter

## Step1. 在Bintray portal上新建空的repo和package

repo name我設成`wisepaas-datahub` packagename根據JCenter上慣例, 規則為groupId:artifactId, 所以我的pkg name為`wisepaas.datahub:cloud-sdk`

## Step2. 根據Portal auto-gen提示去修改project pom.xml和maven setting.xml

在portal建完pkg後, 會順便產生設定讓你複製貼上, 點擊 `Set me up` ![](https://3639912965-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M4wburGGKab7MC2oOVd%2F-M4wbweZ8BSNkeEXgUzh%2F-M4wbzzJw0jON90YTeZz%2Fbintrayhint.PNG?generation=1586933822985272\&alt=media) 接著再點擊`Uploading` > `Deploying with Maven` ![](https://3639912965-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M4wburGGKab7MC2oOVd%2F-M4wbweZ8BSNkeEXgUzh%2F-M4wbzzLMrL83HcptQj8%2Fbintrayhint2.PNG?generation=1586933823267014\&alt=media)

要特別注意, password不是指login pwd, 是一組token, 要從portal產生, 可以看到有兩段cfg,上面那一段是要放在全域maven setting.xml的, 下面那段是要放在專案pom.xml的

pom.xml

```
...
    <distributionManagement>
        <repository>
            <id>bintray-advwacloud-wisepaas-datahub</id>
            <name>advwacloud-wisepaas-datahub</name>
            <url>https://api.bintray.com/maven/advwacloud/wisepaas-datahub/wisepaas.datahub:cloud-sdk/;publish=1</url>
        </repository>
    </distributionManagement>
</project>
```

接著要改setting.xml, 不知道它放哪, 可以下mvn -X, 找到下面兩行, 任選一個來改就行

```
[DEBUG] Reading global settings from xxxx\settings.xml
[DEBUG] Reading user settings from xxxx\settings.xml
```

setting.xml已經有註解掉的範例, 修改它就好

## Step3. mvn deploy推到Bintray上

用VSCODE有按鈕可以直接deploy, 或下指令 `& mvn deploy -f "project-path\pom.xml"`

接著到Bintray portal看到maven info有出現就算成功將project推到Bintray了

![](https://3639912965-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M4wburGGKab7MC2oOVd%2F-M4wbweZ8BSNkeEXgUzh%2F-M4wbzzNOvXf1BVqyT8v%2Fbintrayhint3.PNG?generation=1586933823817678\&alt=media)

## Step4. Bintray上推到JCenter, JCenter才是真正的public repo

![](https://3639912965-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M4wburGGKab7MC2oOVd%2F-M4wbweZ8BSNkeEXgUzh%2F-M4wbzzP35gR3LC3f-IU%2Fbintrayhint4.PNG?generation=1586933824240325\&alt=media) ![](https://3639912965-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M4wburGGKab7MC2oOVd%2F-M4wbweZ8BSNkeEXgUzh%2F-M4wbzzRw_v3FJzIQz7R%2Fbintrayhint5.PNG?generation=1586933823642427\&alt=media)

你很有可能會遇到 `POM project file is not valid.`, 代表你的pom.xml缺少某些欄位

這裡列出幾個常見缺少的, 請檢查一下, 以下範例真的可以填空值

```
  <name>scada</name>
  <description>wisepaas scada sdk</description>
  <inceptionYear></inceptionYear>
  <licenses></licenses>
  <organization></organization>
  <developers></developers>
  <contributors></contributors>
  <scm></scm>
```

送出之後不是馬上上架, 好像還會再審核, 而且我記得它會要你附上source code/doc, 但有一招可以繞過

* 先建一個空資料夾
* 放一個README.md (內容隨意)
* 在相同目錄執行 `jar cvf cloud-sdk-0.0.1-sources.jar *`
* 然後直接用Bintray poratl上傳檔案
* 照上述步驟再做一個 `jar cvf cloud-sdk-0.0.1-javadoc.jar *`

接著回到portal

好像只有第一版本需要這樣審核, 後面的版本不用doc跟source也可以
