Question

我正在尝试在Docker容器中构建/部署Spring Boot。

export default {
  name: 'HelloWorld',
  data() {
    return {
      template: ``,
      column: "hare",
      item: {name: "krishna"},
      msg: 'Welcome to Your Vue.js App'
    }
  },
  created() {
    this.template = `
      <div :class="[c-${this.column}]">
        ....
        <router-link :to="/list/${this.item.name}"> test </router-link>
        ....
      </div>
    `;
  }
}

如您所见，我正在使用第一个mvn命令缓存所有依赖项，以使我的代码应用程序中的每次更改都不会触发新的依赖项下载。它适用于大多数依赖项，但有些仍被下载（即使已缓存）。这是第二个mvn命令（软件包）的日志：

FROM maven:3.5.3-jdk-8-slim AS build
COPY ./pom.xml /app/pom.xml
RUN cd /app
RUN mvn -f /app/pom.xml -s /usr/share/maven/ref/settings-docker.xml dependency:go-offline dependency:resolve-plugins -B
COPY . /app
RUN mvn -f /app/pom.xml -s /usr/share/maven/ref/settings-docker.xml --batch-mode package -DskipTests

（顺便说一句，（0 B / s下的0 B）有点奇怪...只是检查一下？）

如果我根据第一个maven命令之后的步骤启动一个容器（mvn依赖项：...）（应该缓存所有依赖项的容器）

lib似乎在那里，但是我可以在mvn包的日志中看到它：

[INFO]从春季发行版下载：https://repo.spring.io/libs-release/org/codehaus/plexus/plexus-utils/1.5.15/plexus-utils-1.5.15.jar

如果我以脱机模式运行mvn软件包，则失败，因为它无法到达https://repo.spring.io/libs-release。

因此看起来它已被缓存，但是maven仍尝试下载此文件。我已经在我的pom.xml中试过了

root@3281a837a236:/usr/share/maven/ref/repository# ls -lh org/codehaus/plexus/plexus-utils/1.5.15
total 244K

-rw-r--r-- 1 root root   40 Oct 19 12:07 plexus-utils-1.5.15.pom.sha1

但没有效果。

有什么主意吗？谢谢！

我终于使用go-offline-maven-plugin找到了解决方案。

         <plugin>
            <groupId>de.qaware.maven</groupId>
            <artifactId>go-offline-maven-plugin</artifactId>
            <version>1.0.0</version>
            <configuration>
                <dynamicDependencies>
                    <DynamicDependency>
                        <groupId>org.apache.maven.surefire</groupId>
                        <artifactId>surefire-junit4</artifactId>
                        <version>2.20.1</version>
                        <repositoryType>PLUGIN</repositoryType>
                    </DynamicDependency>
                </dynamicDependencies>
            </configuration>
        </plugin>

并尝试使用以下方法获取所有依赖项：

mvn de.qaware.maven:go-offline-maven-plugin:resolve-dependencies

Maven / Docker：缓存所有依赖项
