java - 如何使用 Maven 程序集将类路径属性添加到可执行 jar

Question

我正在使用以下插件来生成可执行 jar。我在我的类路径中有一个属性文件，我想将它添加到我的 jar，但是使用程序集插件我无法做到这一点。我找到了一些答案说我们可以使用 jar 插件创建一个 jar，然后使用 assembly 插件打包它们。任何人都可以帮助我如何做到这一点。

我的插件说明

我通常发现使用 shade 插件更容易。它将运行 jar 所需的所有依赖项捆绑到一个 jar 中，因此您不必修改类路径，一切都在 jar 中:

http://maven.apache.org/plugins/maven-shade-plugin/

示例用法:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.1</version>
            <configuration>
                <minimizeJar>true</minimizeJar>
                <transformers>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass>your.package.Main</mainClass>
                    </transformer>
                </transformers>
                <artifactSet>
                    <excludes>
                        <!-- maybe there is stuff you don't want in the jar -->
                        <exclude>log4j:log4j</exclude>
                        <exclude>org.slf4j:slf4j-api</exclude>
                        <exclude>org.slf4j:slf4j-log4j12</exclude>
                    </excludes>
                </artifactSet>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
