当我从命令行运行应用程序时，是否应该传递任何特殊参数？
这只是一个简单的应用程序，当我从STS运行时，函数可以像我预期的那样工作，但是我只是想更好地理解在运行应用程序时STS&命令行是否有不同的参数

这一行是问题的根本原因：

[警告]org.springframework:spring jdbc:jar:4.3.7.RELEASE的POM无效，可传递依赖项（如果有）将不可用，有关详细信息，请启用调试日志记录

我认为它来自您的maven设置或命令行中的java版本。

我使用带-X参数的maven命令重新运行，因此它将打开调试日志记录

然后错误得到了更清晰的错误信息

当Maven最终下载HTML错误页而不是工件时，我看到过这种情况。您可以尝试在
~/.m2/Repository
处删除本地Maven存储库，然后从命令行生成。
您必须删除.m2文件夹并更改依赖项的版本，然后重试更新Maven项目。
在我的例子中我有两次依赖关系：


<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>




org.springframework.boot
spring引导启动器数据jpa


及



org.springframework.boot
spring引导启动器数据jpa
测试



在删除第二个后，由于我在测试之外需要它，错误消失了。
你可以是mo特定的吗？我的java版本“1.8.0\u 77”我也将java_指向该jdk。我尝试过用谷歌搜索该依赖项错误，但没有成功。您可以使用-X开关重新运行full Debug mode>re run Maven以启用完全调试日志记录。我使用-X运行过，但我无法在此处更新该日志，因为它太长了。好的，我已经发现了问题。很抱歉，我单击enter，它将显示t我的评论。使用-X参数重新运行后，我可以看到一条更清晰的错误消息。这是由损坏的pom文件引起的。有一次，我还发布了一个问题，该问题与未发现类相关，该错误是由损坏的jar引起的。我的问题是，我如何验证我的本地maven存储库是否处于完美状态？感谢为“org.springfr”找到的库amework.data.repository.CrudRepository'
