spring-boot-thin-maven-plugin doesn't work with my maven nexus setup

[ahoehma]

Hi all,

I tried the thin-launcher experiment but I found that behind my company maven/nexus setup it doesn't work,

In my worker environment I don't have direct access to maven central etc. All the maven traffic goes to our internal nexus-server.

So have this maven settings:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

      <mirrorOf>*</mirrorOf>

    </mirror>
  </mirrors>
  <profiles>
    <profile>
      <id>myproject</id>
      <properties>
        <release-server-url>https://internal-server/nexus/content/repositories/releases/</release-server-url>
        <snapshot-server-url>https://internal-server/nexus/content/repositories/snapshots/</snapshot-server-url>
      </properties>
      <repositories>
        <repository>
          <id>nexus</id>
          <url>http://nexus</url>
          <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
          </releases>
          <snapshots>
            <enabled>true</enabled>
            <updatePolicy>always</updatePolicy>
          </snapshots>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>nexus</id>
          <url>http://nexus</url>
          <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
          </releases>
          <snapshots>
            <enabled>true</enabled>
            <updatePolicy>always</updatePolicy>
          </snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
  <servers>
    <server>
      <id>nexus</id>
      <username>XXXXX</username>
      <password>XXXXX</password>
    </server>
  </servers>
</settings>

For all my normal maven builds etc. everything works fine since years (I can just hope the above settings are not nonsense!) 😄

I added the plugin:

<plugin>
   <groupId>org.springframework.boot.experimental</groupId>
   <artifactId>spring-boot-thin-maven-plugin</artifactId>
   <version>1.0.30.RELEASE</version>
   <executions>
      <execution>
          <!-- Download the dependencies at build time -->
          <id>resolve</id>
          <goals>
              <goal>resolve</goal>
          </goals>
          <inherited>false</inherited>
       </execution>
   </executions>
</plugin>

I pimpt the final name of my app:

<properties>
    <finalName>ccupdate</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
....

The I run simply "mvn clean install"

And for me it seems that the maven artifact downloader can't handle my "nexus" thing somehow:

I'm using

$mvn -version

I also tried with these maven settings:

Then I get 401

I noticed that your URLs look inconsistent: you want to use http://nexus in the first example and that doesn't seem to be a correct URL (http protocol for one thing), so I'm guessing it is just getting a 404. The 401 suggests there is an issue with credentials. AFAIK it's supposed to work, but it's a hard thing to test, however the URL also looks odd because you define those properties like release-server-url and then don't use them.

I would actually expect just a mirror would work, but I don't know how a mirror with "mirrorOf=*" is supposed to behave so that might be a problem.
