我试图通过添加或删除project.build.group来修改它，但仍然不起作用。

我总是收到这个错误。

找到几个关于'sourceEncoding‘缺失或无效问题的主题，但没有任何关于'group’缺失或无效错误的主题。

Answer 1

"group“参数不是通常的POM的"groupId”。相反，它指的是通常在文件/usr/share/doc/rpm-$version/GROUPS中定义的RPM的组。plugin docs中提到了这一点。您需要使用正确的组配置RPM插件；如下所示：

<plugins >
...
    <plugin>
       <groupId>org.codehaus.mojo</groupId>
       <artifactId>rpm-maven-plugin</artifactId>
       <version>2.1.5</version>
       <configuration>
           <group>Development/Tools</group>
       </configuration>
    </plugin>
...
</plugins>

Answer 2

当您在某个pom文件中指定rpm插件及其配置并尝试从父目录构建时，会出现此错误。在这种情况下，maven将在所有项目上运行goal rpm:rpm，因此rpm插件也将应用于所有可能没有配置rpm插件的项目。

解决方案：

移出此插件以分离子模块。

在您的案例中，例如创建包含整个配置文件的rpm-package模块：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   <modelVersion>4.0.0</modelVersion>
   <parent>
     <groupId>net.brewspberry</groupId>
     <!-- I would rename it, parent is not rpm anymore -->
     <artifactId>brewspberry-rpm-parent</artifactId>
     <version>0.1.0-SNAPSHOT</version>
   </parent>
   <artifactId>rpm-package</artifactId>
   ...
   <!-- move entire block "profiles" here -->
   <profiles>
     <profile>
       <id>rpm-build</id>
       ...
     </profile>
   </profiles>
 </project>

在您的父pom.xml中：

<modules>
  ...
  <module>rpm-package</module>
</modules>

不要忘记更新映射的源路径。

现在您可以运行：

mvn clean package

此外，如果您也是在Windows上构建，请参阅How do I make this plugin run only on non-Windows platforms?。

在我的例子中，我需要添加...

<properties>
    <project.build.sourceEncoding>utf-8</project.build.sourceEncoding>
</properties>
