我的jar没有运行,我可以告诉它尝试运行,因为log4j文件管理创建日志文件夹,但没有任何反应,日志是空白的.

我的问题是我将jar文件放在名为bin的文件夹中,并将库放在名为lib的文件夹中

我在嘲笑这个:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
    <outputDirectory>${staging.dir}/bin</outputDirectory>
      <archive>
        <manifest>
          <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
          <addClasspath>true</addClasspath>
          <mainClass>com.Main</mainClass>
          <classpathPrefix>../lib/</classpathPrefix>
        </manifest>
      </archive>
    </configuration>
  </plugin>

和

<plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${staging.dir}/lib</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

我也尝试过使用maven-assembly-plugin,但它包装了jar上的所有东西,我真的需要有文件夹bin和lib

我需要设置什么才能使其正常工作？

编辑:META-INF文件

解

原来META-INF文件不正确.原因是maven-archiver-plugin将时间戳重命名为SNAPSHOT库作为默认行为

根据Maven …

嗨，我是liquibase的新手，我在编译它后导入一个现有项目，但遇到构建失败，我无法理解原因和解决方案，我试图理解代码，但是我确实发现了要解决的问题它。

这是运行后的结果 mvn compile

我尝试使用maven 2.2.1构建项目并收到以下错误
请注意"无法创建目录" - 我相信D:是一个由TrueCrypt加密的驱动器,现在实际上是H:(D :仍然是无法通过Windows访问的物理驱动器)

如何让maven尝试在H上安装插件:而不是在D:？

我正在尝试学习 Spring Boot 实践，并使用我的 IntelliJ IDE 通过 Spring Starter 导入基本 Spring Boot 应用程序的样板，但 Maven 无法解析所有依赖项，并且我的项目错过了重要的依赖项。我不明白这是什么原因。

首先，我认为问题出在使用 JDK8 作为较新版本的 SpringFramework，然后我安装了 JDK11，但同样的问题仍然存在，据我所知 POM.xml 列出了其中的所有依赖项。

IDE 的屏幕截图来了解一下
