Docker 仅从本地存储库解析 Maven 工件？

Question

我有一个正在运行的 java spring-boot 应用程序，它从 gitlab 存储库中获取依赖项。

这在本地 mvn package 命令上运行良好。但是，一旦我在本地 docker 容器中执行 mvn 命令，maven 就会尝试从我的 gitlab 存储库中解析 spring 工件。为什么？

Dockerfile:

# syntax=docker/dockerfile:1

FROM maven:3.8.4-eclipse-temurin-11 as dependencies
COPY pom.xml .
COPY settings.xml .
RUN mvn --debug -U -B package -s settings.xml

pom.xml:

<project>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.6</version>
        <relativePath/>
    </parent>
    
     <repositories>
        <repository>
            <id>gitlab-maven</id>
            <url>https://git.example.com/api/v4/projects/295/packages/maven</url>
        </repository>
    </repositories>
    
    <dependencies>
        ...
    </dependencies>
</project>

结果：

[INFO] Scanning for projects...
[DEBUG] Resolving artifact org.springframework.boot:spring-boot-starter-parent:pom:2.6.6 from [gitlab-maven (https://git.example.com/api/v4/projects/295/packages/maven, default, releases+snapshots), central (https://repo.maven.apache.org/maven2, default, releases)]

        <server>
            <id>gitlab-maven</id>
            <configuration>

                    </property>
                </httpHeaders>
            </configuration>
        </server>
    </servers>
</settings>

Answer 1

您的问题是为什么对您的 git 存储库的解析正确？

您正在使用您的回购路径构建 pom，因此它解析为您的回购

 <repositories>
        <repository>
            <id>gitlab-maven</id>
            <url>https://git.example.com/api/v4/projects/295/packages/maven</url>
        </repository>
    </repositories>

Answer 2

这一定是某种缓存问题。我删除了 docker 配置，重新启动机器，现在它可以工作了。

Docker 仅从本地存储库解析 Maven 工件？

Docker resolves maven artifacts only from local repository?
