使用管道構建SpringBootazure函式失敗并出現以下錯誤:無法在本地獲取AzureFunctionsCoreTools版本

2022-06-30 00:33:46 .NET開發

我對 azure 函式比較陌生,我正在嘗試使用由 azure 事件中心訊息觸發的 spring boot 在 java 中創建一個 azure 函式。我使用了我在此處找到的示例 ,并將相關代碼從 HTTP 觸發器更改為事件中心觸發器。

在本地構建它并通過 maven 插件將其部署到 azure 沒有任何問題,但是當我嘗試通過 azure 管道構建此代碼時,我收到以下錯誤:

我的管道代碼:

我發現奇怪的是,如果我只是從觸發器方法中洗掉事件中心注釋而不對代碼和/或 pom 進行任何其他更改,則不會發生錯誤:

  @FunctionName("createAndSendToken")
  public void run(
//      @EventHubTrigger(name = "apiTokenRequests",
//          eventHubName = "api-key-requests",
//          connection = "EventhubConnectionString",
//          consumerGroup = "digiapp",
//          cardinality = Cardinality.ONE)
      String payload,
      final ExecutionContext context
  ) {
    context.getLogger().info("EventHub trigger function execution started");
    context.getLogger().info("payload:"   payload);
    KeyResponse keyResponse = handleRequest(new KeyRequest(payload), context);
    context.getLogger().info("EventHub trigger function execution finished with status "   keyResponse.getStatus());
  }

更奇怪的是:我有一個從另一個不使用 spring 的示例(我不再找到)派生的函式的早期版本。在這里,帶有 eventthub 觸發器的代碼可以由 azure 管道構建,沒有任何問題。該函式的 pom 如下所示:

舊函式觸發器的代碼和注釋與由于某種原因無法構建的新代碼中的相同。

我已經嘗試過不同的事情,比如更改 maven 插件的版本、天藍色庫、函式版本和擴展包版本。等等我還嘗試了不同的構建/代理影像:

pool:
  vmImage: 'ubuntu-latest'

pool:
  vmImage: 'ubuntu-22.04'

但沒有任何幫助。我沒主意了。有人可以幫忙嗎?

關于克里斯蒂安

uj5u.com熱心網友回復:

由于上述原因,我仍然不相信這是最好的解決方案,但根據@khmarbaise 的評論,我通過在呼叫實際構建步驟之前手動將必要的工具安裝到構建代理中來解決我的問題:

          - task: Npm@1
            inputs:
              #this is needed so that the function extension install in the maven task doesn't fail
              command: 'custom'
              customCommand: 'install -g azure-functions-core-tools@3 --unsafe-perm true'
