Question

在删除.m2 /存储库中的所有插件之后，为了解决我遇到的错误，我无法运行我的应用程序。我收到此错误

<?php
$query = mysqli_query($conn,"SELECT * FROM techsupport,techdetails WHERE techsupport.id = techdetails.id");

while ($fetch=mysqli_fetch_array($query)) {

    $ids = $fetch['id'];
    $serv_code = $fetch['service_code'];
    echo "<tr>";
    echo "<td><a href='#' data-target='#editModal$ids' data-toggle='modal' ><i class='fa fa-edit'></i></a></td>";
    echo "<td>".$fetch['id']."</td>";
    echo "<td>".$fetch['service_code']."</td>";
    echo "<td>".$fetch['log_date']."</td>";
    echo "<td>".$fetch['title']."</td>";
    echo "<td>".$fetch['remarks']."</td>";
    echo "<td>".$fetch['status']."</td>";
    echo "<td>".$fetch['parts']."</td>";
    echo "<td>".$fetch['request_date']."</td>";
    echo "<td>".$fetch['received_date']."</td>";
}

?>
            </table>
        </div>
    </div>         
</div>

我的POM非常简单，看起来像：

<div class="modal fade" id="editModal<?php echo $ids;?>" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
  <div class="modal-dialog modal-dialog-centered" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

您知道我该如何纠正吗？在删除存储库插件的内容之前，该应用程序运行良好。 我使用Maven 3.5.2

编辑：当我使用-X运行以获取完整输出时，我得到了：

Answer 1

我试图在日食中使用您共享的pom.xml创建一个Maven项目，当我执行mvn clean install时，它工作得很好。

也许可以检查您的biz/aQute/bnd/bnd-maven-plugin中是否创建了目录路径/.m2/repository/。否则，请尝试删除现有项目，并使用正确的groupId和artifactId创建一个新的maven项目，并确保它们与您的pom.xml中存在的项目匹配。

祝你好运！

Answer 2

尝试清理项目并重新构建。然后检查.m2目录-biz.aQute.bnd:bnd-maven-plugin:jar:3.3.0目录中是否有任何内容？检查其中的pom文件。看起来正确（例如在repository中）？使用-X构建以查看详细日志。 您还可以使用mvn dependency:tree搜索问题-see article。

之后，您还可以尝试手动安装缺少的工件：https://stackoverflow.com/a/46276387

我删除了.m2 / repository文件夹，因为所有插件都已损坏。然后，我重新启动计算机。现在一切正常。非常感谢。
