Question

这是我使用Spring的第一个项目（我对Maven也不太熟悉），在运行mvn package时我在标题中收到错误。

这是我的pom.xml：

当我从version删除executions和spring-boot-maven-plugin时，会发生同样的事情。

Answer 1

在运行mvn install之前尝试spring-boot:repackage：

mvn clean install spring-boot:repackage

Answer 2

好的，我发现了错误。我需要将packaging参数从jar更改为pom。此外，还不需要repositories，pluginRepositories，maven-compiler-plugin和spring-boot-maven-plugin＆＃39; s version和executions

Answer 3

只是添加我的经验：

没有任何建议的解决方案有效。我发现.m2文件夹中下载的spring-boot-maven-plugin存在一些问题。删除插件并允许＆＃34; mvn清理安装＆＃34;重新下载和构建工作。

Answer 4

我已将此配置添加到pom.xml

<plugins>
 <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
      <skip>true</skip>
    </configuration>
 </plugin>
.
.
.
</plugins>

Source

Answer 5

在我的情况下，确切的错误消息是这样的：

无法执行目标 org.springframework.boot：spring-boot-maven-plugin：1.5.14.RELEASE：repackage 无效的条目大小（预期为1，但有0个字节）

我正要创建一个空的干净的Spring Boot项目，并想要构建它，以查看一切是否良好。我发现错误是由空的 application.properties 文件引起的。它已创建，但其中没有任何文本。添加属性（例如server.port：19999）后，该项目已成功构建。

Answer 6

如果您使用的是intelliJ社区，则列出的内容均无效。我切换到Eclipse，并且能够使用start.spring.io中的默认设置运行spring项目，而无需更改POM文件或任何设置。看来intelliJ社区在春季项目中搞得一团糟。

简而言之，请先尝试另一个IDE，然后再进行任何更改。 start.spring.io安装程序应按打包的方式工作。

Answer 7

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Answer 8

如果您的项目是多模块的，请记住应用程序类的位置。我必须做 3 件事才能完成这项工作：

与往常一样，当您对 pom 进行重大更改时，请从您的 IDE 中执行 Maven > 更新项目。

正如其他人所建议的：

mvn clean install spring-boot:repackage

它仍然不起作用...来自我应用程序的父 pom。我的应用程序是 moltimodule，其中一个模块具有 Spring Application 类。只有当我从该模块运行重新打包目标时，我才能正确生成我的胖 jar，否则我会得到：

Execution default-cli of goal org.springframework.boot:spring-boot-maven-plugin:2.4.1:repackage failed: Unable to find main class

因为构建从主类所依赖的模块开始，当然，它们不包含应用程序的主类。

我还在研究为什么，因为我想让我的项目按照反应堆依赖检测的方式一次性构建，而不是分两次构建，除了丑陋之外，对于 CI 自动化来说非常不方便。

目标org.springframework.boot的执行默认值：spring-boot-maven-plugin：1.0.2.RELEASE：repackage failed：Source必须引用现有文件
