I'm using IDEA's bundled maven(3.6.3) installing java-sdk's master branch into my local env, however,

<protocVersion>${protobuf.version}</protocVersion>

in dapr-sdk-autogen and dapr-sdk-examples poms failed. reporting:

it will build correctly after I change it to:

<protocArtifact>com.google.protobuf:protoc:${protobuf.version}</protocArtifact>

according to: os72/protoc-jar-maven-plugin#68

so, why is problem happen, and should we change it to the protocArtifact?

It's been a while the last time we built it on Windows. We don't see this problem on macOS or Linux. I am using the same Maven version as you. Can you repro this on Linux? Just to confirm, this change in settings will not make a difference in the generated code, right? I will confirm by myself but wants to make sure you tested that to catch this early.

I don't have a pure linux dev env, this is what I got building in WLS2 Ubuntu-20.04 distro. And this is the repo I used to build:

    <mirror>
      <id>repo1</id>
      <mirrorOf>central</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>https://repo1.maven.org/maven2/</url>
      <!--<url>http://insecure.repo1.maven.org/maven2/</url>-->
    </mirror>
    <mirror>
      <id>repo2</id>
      <mirrorOf>central</mirrorOf>

    </mirror>
  </mirrors>

They are different.

• using protocVersion will lead to a manually download, mostly from default Central.
• protocArtifact will using maven resolver to download protoc like other depdencies in pom.xml.
  So in case your project using private maven repository, protocArtifact will help to resolve the issue.
