【问题描述】：
我有三个 gradle 模块：一个 JavaEE API、一个 Angular 前端和一个 Gradle 项目，用于将这两个模块打包到一个 EAR 中。
将两者之一打包到 EAR 中，一切正常（API 或前端运行良好）
一旦我将 BOTH（API 和前端）打包到 EAR 中，我在部署时就会收到 ClassNotFoundExceptions：

简而言之：
- 注释掉 API 的依赖关系并注释掉 API webModule == WORK
- 注释掉 FrontEnd 的依赖并注释掉 FrontEnds webModule == WORK
- 在依赖项和 webModule == ClassNotFound 中都添加注释
我阅读了很多，尝试了很多，但现在我不知道该寻找什么。
EAR 部署处理器
ear {
deploymentDescriptor {
version = "6"
initializeInOrder = true
applicationName = "My-App"
displayName = "My-App"
libDirName = "/lib"
// WARs
webModule(project(':MyAppClient').name + '-' + project(':MyAppClient').version + '.war', "/client/client")
webModule(project(':MyAppServerAPI').name + '-' + project(':MyAppServerAPI').version + '.war', "/api/api")
}
}
API 依赖项
dependencies {
//////////////////////////////////////
// Third party dependencies
//////////////////////////////////////
// Logging
compile 'org.slf4j:slf4j-api'
// JavaEE
compileOnly 'javax:javaee-api'
// Jackson Json
compile 'com.fasterxml.jackson.core:jackson-core'
compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider'
//apache commons
compile group: 'org.apache.commons', name: 'commons-lang3'
}
EAR 的 application.xml
<?xml version="1.0"?>
<application xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_6.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="6">

问题不属于 Angular。在另一个用例中，我有一个依赖于项目的另一个模块的 WAR，在从模块 A 部署依赖于模块 B 的 WAR 时发生 JavaEE 和类似问题
【问题讨论】：
-
您可能缺少 webapp/lib 目录中的库。你能列出那里的罐子吗？
-
它们与 tge WAR 处于同一级别。平在耳朵里。他们应该在其他地方吗？
-
大多数时候，您只需将文件包含在每个 war 或 EJB 的 WEB-INF/lib 目录中，而不必太担心。如果您绝对不希望重复（压缩存档中的重复文件不会占用额外空间），请发布您的 ear 部署描述符，我们可以将您指向您需要包含的元素
-
@JonathanS.Fisher 感谢您的帮助。我更新了描述。 （在我的应用程序中，我没有 EJB）
-
@JonathanS.Fisher 抱歉没有回复。有几天是AFK。看我的回答。感谢您的想法和时间:)
