Question

嗨，我是Maven技术的新手，我正在尝试创建和运行Maven项目，但遇到了构建失败错误。在运行无法找到/加载主类的项目编译器时。我找不到确切的错误是什么。请帮助我。

先谢谢了。

错误：

                Sheet sheet = wb1.getSheetAt(0);// getting sheet at 0
                System.out.println("Sheet name is:>>>>"+sheet.getSheetName());

                Row row1 = sheet.getRow(0);
                Iterator cellIter=row1.cellIterator();

                while(cellIter.hasNext()){

Answer 1

在使用url maven检索jackson-databind工件后，我假设您正在使用镜像。

尝试注释掉settings.xml中的任何镜子标签。您可以在计算机上以下位置之一找到settings.xml文件：

$ {maven.home} /conf/settings.xml
$ {user.home} /。m2 / settings.xml

Answer 2

在settings.xml中更新镜像的凭据

<servers>
...
        <server>
            <id>MY-REPO</id>
            <username>MYREPO-USER</username>
            <password>MYREPO-PASS</password>
        </server>
</servers>

<mirrors>
        <mirror>
            <id>MY-REPO</id>
            <mirrorOf>central</mirrorOf>
            <name>Mirror </name>
            <url>https://ci-repo.aexp.com/java-proxy/content/repositories/prod/</url>
        </mirror>
...
<mirrors>

在此示例中，MY-REPO是ci-repo.aexp.com镜像的ID 凭据与您在网络浏览器中打开https://ci-repo.aexp.com/java-proxy/content/repositories/prod/所使用的凭据相同

我面临类似的问题。我通过在IDE中更改一些配置来解决它。我使用WebSphere（由Eclipse技术提供支持）。我希望以下步骤也能对您有所帮助。

在IDE中，请单击窗口>首选项> Java EE> Maven> Maven存储库初始化。如果settings.xml文件不存在，则页面将显示以下文本：settings.xml文件不存在。要创建此文件并配置IBM Maven存储库，请单击配置。此操作在settings.xml文件中配置IBM Maven存储库，并注册原型目录的URL。

settings.xml文件的位置由“窗口”>“首选项”>“ Maven”>“用户设置”页面中设置的值确定。（如果需要：要更改文件位置，请单击“用户设置文件”链接直接转到首选项页面。）

此外，当您创建一个新的工作区时，默认情况下Maven存储库索引功能是关闭的。请单击窗口>首选项> Maven，然后选择启动时下载下载存储库索引更新。

希望这会有所帮助！
