_*Note:* I am trying to do a build behind a firewall which means I cannot access the Internet, I can only access my internal Maven repository inside my network, so:_ - _grabbing artifacts from https://artifacts.example.com/repository/maven/ works fine_ - _grabbing artifacts from anywhere fails (due to firewall restrictions)_ Let's begin: My {{pom.xml}} has the following: {code:xml} ... <dependencies> ... <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>${spring.boot.version}</version> </dependency> ... </dependencies> ... <repositories> ... <repository> <id>central</id> <name>Public</name> <url>https://artifacts.example.com/repository/maven/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> ... </repositories> ... {code} The {{dependency:tree}} for the Spring Boot dependency above is as follows: {code:java} +- org.springframework.boot:spring-boot-starter-web:jar:2.0.0.RELEASE:compile | +- org.springframework.boot:spring-boot-starter-json:jar:2.0.0.RELEASE:compile | | +- com.fasterxml.jackson.datatype:jackson-datatype-jdk8:jar:2.9.4:compile | | +- com.fasterxml.jackson.datatype:jackson-datatype-jsr310:jar:2.9.4:compile | | \- com.fasterxml.jackson.module:jackson-module-parameter-names:jar:2.9.4:compile | +- org.springframework.boot:spring-boot-starter-tomcat:jar:2.0.0.RELEASE:compile | | \- org.apache.tomcat.embed:tomcat-embed-websocket:jar:8.5.28:compile | +- org.hibernate.validator:hibernate-validator:jar:6.0.7.Final:compile | | +- javax.validation:validation-api:jar:2.0.1.Final:compile | | +- org.jboss.logging:jboss-logging:jar:3.3.0.Final:compile | | \- com.fasterxml:classmate:jar:1.3.1:compile | \- org.springframework:spring-web:jar:5.0.4.RELEASE:compile {code} How is it that the build fails as such: {code:java} ...

When you go down the Spring Boot rabbit hole (go into the {{spring-boot-starter-web}}'s {{pom.xml}} and then traverse up it parent-pom structure a few jumps, you'll eventually get to a parent-pom {{spring-boot-dependencies}} with this definition: {code:java} ... <repositories> <repository> <snapshots> <enabled>false</enabled> </snapshots> <id>spring-milestone</id> <name>Spring Milestone</name> <url>https://repo.spring.io/milestone</url> </repository> <repository> <snapshots> <enabled>true</enabled> </snapshots> <id>spring-snapshot</id> <name>Spring Snapshot</name> <url>https://repo.spring.io/snapshot</url> </repository> <repository> <snapshots> <enabled>false</enabled> </snapshots> <id>rabbit-milestone</id> <name>Rabbit Milestone</name> <url>https://dl.bintray.com/rabbitmq/maven-milestones</url> </repository> </repositories> ... {code} *How is it that the Maven build does not even attempt to reach out to [https://artifacts.example.com/repository/maven/] to try to find the missing dependency {{shrinkwrap-bom}}? and only reaches out to the above repos only? *This seems like a transitive dependency resolution bug to me as the Maven build does not even make a single attempt at trying to get {{shrinkwrap-bom}} from the repository that I have explicitly defined in my {{pom.xml}}.* -- This message was sent by Atlassian JIRA (v7.6.3#76005)
