有一个 README.md 文件，其中包含转换为 pom.xml 文件值的各种文本占位符。该文件位于路径上{project.basedir}/doc/README.md，并且在构建项目时，它由maven-resources-plugin 插件处理，该插件将文本占位符转换并将其复制到项目根目录，并在下一步中复制到目标目录（所以它也在 JAR 根目录中）：

README.md 文件的内容示例：

# ${project.name}

${project.description}

[[_TOC_]]

## Used Maven Dependencies

- [JUnit](https://junit.org/junit5/docs/${junit}/api/) v.${junit}
- [SELF4J](https://www.javadoc.io/static/org.slf4j/slf4j-api/${slf4j}/index.html) v.${slf4j}
- ...

## Build

Compiled and built at ${timestamp} with:

- Java: ${java.version}
- Maven: ${maven.version}

```xml
<dependency>
    <groupId>${project.groupId}</groupId>
    <artifactId>${project.artifactId}</artifactId>
    <version>${project.version}</version>
</dependency>
```

在 pom.xml 文件中，处理配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<project ...>
  <!-- ... -->
  <properties>
    <timestamp>${maven.build.timestamp}</timestamp>
    <maven.build.timestamp.format>yyyy-MM-dd HH:mm</maven.build.timestamp.format>
    <!-- ... -->
  </properties>
  <!-- ... -->
  <build>
    <!-- ... -->
    <plugins>
      <plugin>

            <configuration>
              <outputDirectory>${project.basedir}</outputDirectory>
              <resources>
                <resource>
                  <directory>${project.basedir}/doc</directory>
                  <includes>
                    <include>README.md</include>
                  </includes>
                  <filtering>true</filtering>
                </resource>
              </resources>
              <encoding>UTF-8</encoding>
            </configuration>
          </execution>
          <execution>
            <id>copy-readme-to-output</id>
            <phase>compile</phase>
            <goals>
              <goal>copy-resources</goal>
            </goals>
            <configuration>
              <outputDirectory>${project.build.outputDirectory}</outputDirectory>
              <resources>
                <resource>
                  <directory>${project.basedir}</directory>
                  <includes>
                    <include>README.md</include>
                  </includes>
                </resource>
              </resources>
              <encoding>UTF-8</encoding>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

问题在于，为了执行所有这些转换，必须通过 maven（例如mvn verify）在本地机器上构建，因为 否则，修改后的 README.md 文件将出现在程序集/JAR 文件中，但不在存储库中。例如，在 pom.xml 中某个依赖项的版本发生了变化，而在 README.md 文件中使用了旧版本/引用。

问题：是否有可能以任何方式配置 README.md 文件的自动生成，即使在本地机器上，甚至在 GitLab 端（在 gitlab-ci.yml 中注册）？理想情况下，我们希望在每次提交时生成一个文件并自动将其“推送”到存储库中。

将项目推送到heroku时，我在maven中遇到错误：

我很尴尬的是正在下载jdk 1.8：

远程：-----> 安装 OpenJDK 1.8... 完成

所以我在application.properties中设置了java.runtime.version=11，我在项目结构中也设置了11，在rum文件中，但是还是下载了1.8

我知道 pom 文件中有一些不喜欢的地方，尤其是在 maven 插件中，但是究竟需要更改什么？

我为 1.18.2 版本创建了一个项目，尝试构建时有很多错误。

错误之一：

bad class file: /C:/Users/fokus/.m2/repository/io/papermc/paper/paper-api/1.18.2-R0.1-SNAPSHOT/paper-api-1.18.2-R0.1-20220614.230913-165.jar!/org/bukkit/entity/Player.class
    class file has wrong version 61.0, should be 56.0
    Please remove or make sure it appears in the correct subdirectory of the classpath.
