To resolve the problem, try to find and remove the * < app >.war.failed*file.

要解决此问题，请尝试查找并删除* < app >.war.failed*文件。

You can use 2 method in this kind of error :

您可以在这种错误中使用 2 种方法：

• in standalone.xml and remove the duplicate resource or in localhost:19990/console/App.html, you can too remove the duplicate resource

• 在standalone.xml中删除重复的资源或者在localhost:19990/console/App.html中，你也可以删除重复的资源

Under standalone/configuration/standalone-full.xml remove the duplicate deployment value.

在 standalone/configuration/standalone-full.xml 下删除重复的部署值。

Remove the below if mywar.war is the duplicate one.

如果 mywar.war 是重复的，请删除以下内容。

<deployments>
    <deployment name="mywar.war" runtime-name="mywar.war">
        <content sha1="d642ffaa51228ab567439653a0923c69b7972cf5"/>
    </deployment>
</deployments>

I also face this same issue, this is bug in JBOSS 8 version for this i follow the below steps to resolve this

我也面临同样的问题，这是 JBOSS 8 版本中的错误，我按照以下步骤解决此问题

1. remove *.failed files from deployments folder

2. comments below lines in standalone.xml file

   <extension module="org.wildfly.extension.undertow"/>

1. 从部署文件夹中删除 *.failed 文件

2. 在standalone.xml 文件中的行下面的注释

   <extension module="org.wildfly.extension.undertow"/>

and this complete subsystem tag

和这个完整的子系统标签

<subsystem xmlns="urn:jboss:domain:undertow:1.2">
</subsystem>

1. restart JBoss
2. again remove *.failedfiles from deployement folder

3. uncomment step 2 means uncomment this tag

   <subsystem xmlns="urn:jboss:domain:undertow:1.2">

3. 重启 JBoss
4. 再次*.failed从部署文件夹中删除文件

5. 取消注释步骤 2 表示取消注释此标签

   <subsystem xmlns="urn:jboss:domain:undertow:1.2">

and

和

`<extension module="org.wildfly.extension.undertow"/>`

this line from standalone.xtml.

这行来自standalone.xml。

If you found removed this subsystem tag and above line from standalone.xml then copies these from standalone-full.xhtml.

如果您发现从 standalone.xml 中删除了这个子系统标签和上面的行，那么从 standalone-full.xhtml 复制这些。

1. restart the jboss and now this duplicate resource issue is resolved :)

6. 重新启动 jboss，现在解决了这个重复资源问题:)

Maybe some .jar was corrupted inside your maven local repository.

也许某些 .jar 在您的 Maven 本地存储库中已损坏。

Delete all in %UserProfile%\.m2\repositorydirectory, build and try again.

删除%UserProfile%\.m2\repository目录中的所有内容，构建并重试。

I ran into the same issue. wildfly was also creating .failed files in standalone/configuration folder. To fix this,

我遇到了同样的问题。Wildfly 还在独立/配置文件夹中创建 .failed 文件。为了解决这个问题，

• i removed all the .failed files.

• cleaned up the contents from deployments, tmp and data folders.

• started the server without any war/ear deployed. It was able to start clean.

• stopped the jboss and added the war/ear and started again

• 我删除了所有 .failed 文件。

• 清理部署、tmp 和数据文件夹中的内容。

• 在没有部署任何战争/耳朵的情况下启动了服务器。它能够开始干净。

• 停止了 jboss 并添加了战争/耳朵并重新开始

now it works fine. Looks like this is a known issue in WildFly https://issues.jboss.org/browse/WFCORE-495

现在它工作正常。看起来这是 WildFly https://issues.jboss.org/browse/WFCORE-495 中的一个已知问题

Hope this helps..

希望这可以帮助..

If this does not help. Next action to perform would be: - Open the standalone.xml or standalone-full.xml (depending on which one is being used)

如果这没有帮助。下一步要执行的操作是： - 打开 standalone.xml 或 standalone-full.xml （取决于使用的是哪一个）

• find deployment-scanner tag. Most certainly it will have two or more entries.

• keep the entry mentioned below and remove all others:

• 找到部署扫描仪标签。肯定会有两个或更多条目。

• 保留下面提到的条目并删除所有其他条目：

deployment-scanner path="deployments" relative-to="jboss.server.base.dir" ....

部署扫描器路径="部署"相对于="jboss.server.base.dir" ....

• clear all the .failed files as well as tmp and data folders.

• try now to start jboss wildfly (you can add the war/ear again from eclipse jboss plugin).

• 清除所有 .failed 文件以及 tmp 和 data 文件夹。

• 现在尝试启动 jboss wildfly（您可以从 eclipse jboss 插件再次添加 war/ear）。

Thanks to @i2ijeya, I could solve thr problem. In my case, the XML block of deploymentswas in standalone/configuration/standalone-full.xmlpath.

感谢 @i2ijeya，我可以解决 thr 问题。就我而言，部署的 XML 块在standalone/configuration/standalone-full.xml路径中。
