这个问题是基于教程Build a Batch Pipeline with Maven Archetypes (Scala)的最小可重复示例，尽管我们无法在为客户构建的管道中使用模式工件。
我们有一个单独的存储库，我们想从中发布（mvn deploy）模式。我们运行相当于（替换djv为您自己的唯一字符串）的设置：
$ 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
主要症状
在 OLP 门户中，我可以在模式列表中看到我的新模式。它解释说我可以像这样添加对它的依赖：
<dependency>
<groupId>com.example.djv.nodecardinality</groupId>
<artifactId>schema_v1_scala_2.11</artifactId>
<version>1.0.0</version>
<type>jar</type>
</dependency>
但是，我无法下载processor项目中的工件：
$ cd processor
$ mvn install
...

...
我们看到这个失败只是因为我们在为项目运行processor的同一台机器上运行项目构建，mvn deploy因此缓存schema中存在一些文件。~/.m2如果没有这些文件，下载就会失败：

次要症状
正如我们在上面看到的，mvn deploy从本地schema目录运行并不会将构建所需的所有内容都放入本地~/.m2存储库（即构建processor子项目）。要将所需文件放入本地~/.m2存储库，我们需要从模式存储库mvn install的父目录 ( ) 运行。nodecardinality
这使我们至少可以在本地（临时）进行开发。
部分分辨率
按照依赖管理·OLP SDK页面上的工件服务部分中的说明进行操作。尽管构建变得更远，但它仍然无法提取依赖项：
