maven 编译错误 - [ERROR] 不可解析的导入 POM：无法传输工件

Question

Maven 新手，可能是新手错误。

我正在做 jenkins 课程的复数介绍。 在其中我们克隆了 git 存储库http://github.com/g0t4/jenkins2-course-spring-boot在其子目录jenkins2-course-spring-boot\\spring-boot-samples\\spring-boot-sample-atmosphere有以下 pom.xml 文件：

当我尝试使用 mvn compile 进行编译时，我收到以下错误的构建日志：

java版本是：

java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)

Maven 版本是：

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: C:\ProgramData\chocolatey\lib\maven\apache-maven-3.6.3\bin\..

Answer 1

这似乎是不阅读评论和@khmarbaise 建议的混合体。

在 pom.xml 中它说：

        <parent>
                <!-- Your own application should inherit from spring-boot-starter-parent -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-samples</artifactId>
                <version>1.4.0.BUILD-SNAPSHOT</version>
        </parent>

因此，当我按照评论建议将 artifactId 更改为 spring-boot-starter-parent 并将版本更新为 2.2.4.RELEASE 时，@khmarbaise 建议我得到以下 pom.xml 的父元素：

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.4.RELEASE</version>
    </parent>

然后用mvn compile我就可以成功编译了。

Answer 2

我也开始看同样的课程，并发出同样的问题。
你给出的答案只是部分正确。 将版本更改为2.2.4.RELEASE将导致您在尝试运行mvn test时遇到许多错误，因为在以后的版本中一些类被抛出（例如org.springframework.boot.autoconfigure.PropertyPlaceholderAutoConfiguration ）。 最好的解决方案是将 artifactId 更改为spring-boot-starter-parent如您所说并将版本更改为1.4.0.RELEASE并且您将能够运行所有 maven 命令而不会出错。 所以，让我们说，完整的答案是：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.0.RELEASE</version>
</parent>

Answer 3

多个 pom.xml 文件引用了不再可用的库的 BUILD-SNAPSHOT 版本。 以下步骤对我有用：-

1. 创建您的 github 帐户
2. Fork 仓库https://github.com/g0t4/jenkins2-course-spring-boot
3. 将分叉存储库克隆到本地目录（比如 /user/ponson/jenkins2-course-spring-boot）
4. 打开 bash 终端并将当前目录更改为本地 git 目录（/user/ponson/jenkins2-course-spring-boot）
5. 运行以下命令以在 pom.xml 文件 find 中将出现的 '1.4.0.BUILD-SNAPSHOT' 替换为 '1.4.0.RELEASE'。 -name pom.xml | xargs sed -i 's/1.4.0.BUILD-SNAPSHOT/1.4.0.RELEASE/g'
6. 打开 spring-boot-dependencies/pom.xml 进行编辑并将 '4.3.2.BUILD-SNAPSHOT' 替换为 '4.3.2.RELEASE'
7. 使用命令“git add”将您的更改暂存到本地存储库。
8. 提交您的更改（git commit -m '<>'）
9. 将更改推送到远程 git 存储库（git push origin）。 随身携带您的 github 凭据并在出现提示时输入。

修复程序在下面的分叉存储库中可用。 也许你可以直接使用它。 https://github.com/PonsonT/jenkins2-course-spring-boot
