如何使用已发布的OLP模式依赖关系？

标签： maven here-olp

此问题是基于教程Build a Batch Pipeline with Maven Archetypes (Scala)的最小可重现示例，尽管我们无法在为客户建立的管道中消耗架构工件。

我们有一个单独的存储库，我们要从中发布（!/usr/bin/python import cv2 import numpy as np def fun(name): return 4 ./embedpy an fun download.jpeg ）模式。我们运行的设置等效于（用您自己的唯一字符串替换mvn deploy）：

djv

主要症状

在OLP Portal中，我可以在模式列表中看到我的新模式。它说明我可以像这样添加依赖项：

$ mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo.archetypes \
                         -DarchetypeArtifactId=pom-root \
                         -DarchetypeVersion=1.1 \
                         -DgroupId=com.example.djv \
                         -DartifactId=nodecardinality \
                         -Dversion=1.0.0 \
                         -Dpackage=com.example.djv.nodecardinality
...
$ cd nodecardinality
$ mvn archetype:generate -DarchetypeGroupId=com.here.platform.schema \
                         -DarchetypeArtifactId=project_archetype \
                         -DarchetypeVersion=1.0.13 \
                         -DgroupId=com.example.djv.nodecardinality \
                         -DartifactId=schema \
                         -Dversion=1.0.0 \
                         -Dpackage=com.example.djv.nodecardinality.schema \
                         -DmajorVersion=1
...
$ cat << EOF > schema/proto/src/main/proto/com/example/djv/nodecardinality/schema/v1/schema.proto
syntax = "proto3";
> 
> package com.example.djv.nodecardinality.schema.v1;
> 
> message NodeCardinalityPartition {
>   repeated NodeCardinality node_cardinality = 1;
> }
> 
> message NodeCardinality {
>   string id = 1;
>   uint32 cardinality = 2;
> }
> EOF
$ # <edit schema/ds/pom.xml per the tutorial>
$ cd schema
$ mvn deploy

但是，我无法在<dependency> <groupId>com.example.djv.nodecardinality</groupId> <artifactId>schema_v1_scala_2.11</artifactId> <version>1.0.0</version> <type>jar</type> </dependency> 项目中下载工件：

processor

我们看到此失败仅是因为我们在为$ cd processor $ mvn install ...

这使我们至少可以在本地（临时）发展。

部分分辨率

按照Dependency Management · OLP SDK页上的工件服务部分中的说明进行操作。尽管构建的步伐进一步加快，但仍然无法消除依赖关系：

processor

OLP模式已部署到HERE Artifact Service。该服务需要特殊授权。为了下载模式或Java / scala绑定，您应该在项目中包括Maven Wagon。请参阅https://developer.here.com/olp/documentation/sdk-developer-guide/dev_guide/topics/dependency-management.html

中的“工件服务”部分

简而言之：

将旅行车的版本添加为属性：

 <artifact.wagon.version>1.6.1</artifact.wagon.version>

将占位符存储库添加到存储库列表中：

  <repositories>
    <repository>
      <id>HERE_PLATFORM_ARTIFACT</id>
    <layout>default</layout>
    <url>here+artifact-service://artifact-service</url> 
  </repository>
  </repositories>

将插件参考放入构建部分：

 <extensions>
  <extension>
    <groupId>com.here.platform.artifact</groupId>
    <artifactId>artifact-wagon</artifactId>
    <version>${artifact.wagon.version}</version>
  </extension>
</extensions>

请注意，您需要保存在~/.here目录中的有效“ credentials.properties”文件。如何获取，请阅读https://developer.here.com/olp/documentation/sdk-developer-guide/dev_guide/topics/get-credentials.html

最好的问候， 迪玛

答案 1 :(得分：0)

问题是使用父Maven项目进行部署。请参阅问题中最后一个错误的最后一句话：

Could not find artifact com.example.djv:nodecardinality:pom:1.0.0 in HERE_PLATFORM_REPO

当我们从com.example.djv:nodecardinality:pom:1.0.0目录运行mvn deploy时，从未上传schema POM。您无法从顶级mvn deploy目录运行nodecardinality。

简单的解决方案是在运行pom.xml之前从schema目录中的mvn deploy删除父项目指针：

  <!-- <parent>
    <artifactId>nodecardinality</artifactId>
    <groupId>com.example.djv</groupId>
    <version>1.0.0</version>
  </parent> -->
