在“更新服务器部署扫描器: WildFly 23”期间发生了内部错误

Question

我试图连接到我的http://localhost：8080/spring test/ui，但不幸的是，我失败了，因为我在Eclips上有错误。WildFly 23理论上有效，因为我通常会得到他们的本地主机

An internal error occurred during: "Updating Deployment Scanners for Server: WildFly 23".
Could not initialize class org.wildfly.security.auth.client.DefaultAuthenticationContextProvider

An internal error occurred during: "Checking Deployment Scanners for server".
Could not initialize class org.wildfly.security.auth.client.DefaultAuthenticationContextProvider

当我尝试将standalone.xml中的目录重定向到具有META和WEB的目标时，我遇到了两个错误。

ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) WFLYDS0011: The deployment scanner found a directory named META-INF that was not inside a directory whose name ends with .ear, .jar, .rar, .sar or .war. This is likely the result of unzipping an archive directly inside the C:\Users\adame\eclipse-workspace\spring-boot-test\target directory, which is a user error. The META-INF directory will not be scanned for deployments, but it is possible that the scanner may find other files from the unzipped archive and attempt to deploy them, leading to errors.

Answer 1

在尝试从Eclipse (2021-09)启动Wildflix19.1.0容器时，我也犯了同样的错误。这个容器似乎开始成功了，但是这个信息让我发疯了。

过了一段时间，我在野生苍蝇谷歌群组上看到了这条消息，这解决了我的问题！

将--add-opens=java.base/java.security=ALL-UNNAMED添加到eclipse.ini解决了我这边的问题

感谢原作者拉希姆·阿利扎达( Rahim Alizada )在OuPrpsF2pY/m/xLit6u-IfBgAJ。

选项--add-opens在运行时打开通知模块(所有类型和成员)，允许来自目标模块的深度反射(在本例中，所有其他模块都未命名)。

在9月261中有更多关于这个选项的信息。

我试着在我的系统中只使用Java 8运行Eclipse，如果我清楚地记住它，我就让它正常工作，但是在这些较新的Eclipse版本上的一些模块需要正确加载Java 11。

在eclipse中部署通配符23服务器时，我遇到了这个错误。

在“更新服务器部署扫描器: WildFly 23”期间发生了内部错误。无法初始化类org.wildfly.security.auth.client.DefaultAuthenticationContextProvider

这也解决了我将--add-opens=java.base/java.security=ALL-UNNAMED添加到eclipse.ini中的问题
