BUILD FAILED

我们正在将WildFly升级到版本19。遇到上述错误，我不太了解。有人可以解释这个错误吗？我是新来的。

Answer 1

首先要意识到的是错误所在

Cannot find parent: com.sun.xml.bind:jaxb-bom-ext for project: com.sun.xml.bind.mvn:jaxb-parent:pom:null

因此，即使我不知道该Bubblegateway是什么，我还是故意说这个POM不在您的本地存储库中。例如，要在eclipse中查找本地存储库，请注意maven设置，应指定路径。

在此存储库中，文件夹就像您的错误消息中的名称。因此文件夹结构应该像

com/sun/xml/bind/2.3.1

在“：”后面的是artifactId。这是.pom或.jar文件的重要名称部分。

所以他要查找的文件应该是：jaxb-bom-ext.pom

我敢打赌他找不到。自己看看，我可能会弄错。

现在如何获取它：

from the specified remote repositories:
central (http://repo1.maven.org/maven2),
bubbleGateway (http://example.com:8081/repository/public/)

他正在查看您的预定义存储库，我想您确实在maven设置文件中对其进行了设置，但是您也可以在其他位置进行设置。关键是，调用http://repo1.maven.org/maven2不再有用，因为它在一段时间前已移至安全站点https://repo1.maven.org/maven2。

在浏览器中检出它，第一个会给您501。后者会给您一个运行中的存储库，您可以在其中找到pom。

所以基本上，您所要做的就是，如果我没记错的话，找到定义存储库的位置，然后添加“ s”;）

祝你好运。
