在依赖项目中包含来自 JAR 的文件

Question

我想跨多个项目同步 log4j 和 logback 配置文件。我有一个包含 log4j 和 logback 依赖项以及配置文件的项目（项目 A）。

项目 A

src/test/resources
- log4j2.xml
- logback-test.xml

项目 B 依赖于项目 A。我想在项目 A 的 JAR 中包含日志配置文件，并在解析项目 B 的 Maven 依赖项时将它们自动放入项目 B 的特定目标文件夹中。

我在项目 A 中尝试过 maven-jar-plugin，但它似乎不适合我的目的。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>3.2.2</version>
    <configuration>
        <includes>
            <include>src/test/resources/log4j2.xml</include>
            <include>src/test/resources/logback-test.xml</include>
        </includes>
    </configuration>
</plugin>

如有任何帮助，我们将不胜感激。

谢谢！

更新：

虽然接受了 Eugene 的回答，但我需要添加一个 <resources> 条目，以便将日志配置文件包含在打包的 JAR 中。

<build>
    <resources>
        <resource>
            <directory>src/test/resources</directory>
            <includes>
                <include>log4j2.xml</include>
                <include>logback-test.xml</include>
            </includes>
        </resource>
    </resources>
</build>

从项目 A 执行 mvn clean compile assembly:single deploy 创建并部署了包含日志文件的 JAR。

[INFO] --- maven-remote-resources-plugin:1.7.0:bundle (default) @ project-a ---
[INFO] Writing META-INF/maven/remote-resources.xml descriptor with 2 entries

从项目 B 执行 mvn clean compile 将文件复制到输出目录

[INFO] --- maven-remote-resources-plugin:1.7.0:process (default) @ project-b ---
[INFO] Preparing remote bundle com.my.projects:project-a:1.0-SNAPSHOT
[INFO] Copying 2 resources from 1 bundle.

Answer 1

请不要将日志记录配置文件放入 JAR 中，如果有人依赖您的 JAR，您的配置可能会覆盖他们的。这取决于首先加载哪个 JAR

如果你愿意，像这样。并将它们打包成 JAR

src/main/resources
- log4j2.xml
- logback.xml

Answer 2

您可以使用Apache Maven Remote Resources Plugin

This plugin is used to retrieve JARs of resources from remote repositories, process those resources, and incorporate them into JARs you build with Maven.

A very common use-case is the need to package certain resources in a consistent way across your organization. For example at Apache, it is required that every JAR produced contains a copy of the Apache license and a notice file that references all used software in a given project

在项目 A 中定义要共享的资源或更好地为共享资源创建单独的项目

    <build>
        <plugins>
            <plugin>
                <artifactId>maven-remote-resources-plugin</artifactId>
                <version>1.7.0</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>bundle</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <resourcesDirectory>src/test/resources/</resourcesDirectory>
                    <includes>
                        <include>log4j2.xml</include>
                        <include>logback-test.xml</include>
                      </includes>
                </configuration>
            </plugin>
        </plugins>
    </build>

Maven 将创建 resources bundle file 用于共享资源 ${basedir}/target/classes/META-INF/maven/remote-resources.xml

<remoteResourcesBundle xsi:schemaLocation="http://maven.apache.org/remote-resources/1.1.0 https://maven.apache.org/xsd/remote-resources-1.1.0.xsd"
    xmlns="http://maven.apache.org/remote-resources/1.1.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <remoteResources>
    <remoteResource>log4j2.xml</remoteResource>
    <remoteResource>logback-test.xml</remoteResource>
  </remoteResources>
  <sourceEncoding>UTF-8</sourceEncoding>
</remoteResourcesBundle>

见documentation

配置其他模块使用共享资源

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-remote-resources-plugin</artifactId>
                <version>1.7.0</version>
                <configuration>
                    <outputDirectory>[your output directory]</outputDirectory>
                    <resourceBundles>
                        <!--The resource bundles that will be retrieved and processed. For example: org.test:shared-resources:${project.version}-->
                        <resourceBundle>groupId:artifactId:version[:type[:classifier]]</resourceBundle> 
                    </resourceBundles>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>process</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

备选方案：
Apache Maven Dependency Plugin 它可以将 and/or 解压工件从本地或远程存储库复制到指定位置。
那里有描述 Maven: Extract dependency resources before test 还有Use a dependency's resources?

更新：
如何添加资源的示例：

<project>
 ...
 <build>
   ...
   <resources>
     <resource>
       <directory>[your folder 1 here]</directory>
     </resource>
     <resource>
       <directory>[your folder 2 here]</directory>
     </resource>
   </resources>
   ...
 </build>
 ...
</project>
