Question

我在Eclipse下开发了一个安装了JBoss工具的项目。当我将应用程序部署到Jboss服务器时，一些通过Maven可用于项目的帮助程序jar文件不会复制到WEB-INF / lib文件夹中。因此，我在运行时得到ClassNotFound异常。

是否有任何方法可以说服Eclipse（或Maven）在部署时将jar文件复制到lib文件夹中？

编辑：pom.xml看起来像：

工件myAuxiliaryStuff应部署在WEB-INF/lib下的jboss部署服务器下。

使用：

Eclipse：Juno Service Release 1
Jboss：7.1.1。最终
m2e 1.3.1.20130219-1424
eclipse web tools platform 3.4.2.v2013

稍后编辑：jboss'日志文件中报告的错误如下：

Answer 1

Eclipse和插件有点挑剔。这就是我为了让它发挥作用而做的。

Project -> Properties -> Deployment Assembly
Add...
Java Build Path Entries (Next >)
Maven Dependencies (Finish)

“部署属性”面板现在应包含Source：Maven Dependecies - ＆gt;的条目。部署路径：WEB_INF / lib

Answer 2

这很可疑：

java.lang.NoSuchFieldError: FLOW

如果我没弄错的话，这与JSF有关。我有一些建议，但我不是任何方面的专家。

首先尝试为此provided和jsf-api添加jsf-impl依赖范围（因为JBoss有它们）：

<dependency>
    <groupId>com.sun.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.2.0-m09</version>
    <scope>provided</scope>   // <----- do it for both
</dependency>

AFAIK，JBoss 7.1.1已经有了JSF 2.1.7。所以，如果你真的需要JSF 2.2，你应该更新JBoss中的JSF模块。以下是Migration to JSF 2.2的方法。

另一种选择是将JSF捆绑到WAR中，并通知JBoss排除容器版本（JBoss附带的版本）：

web.xml 中的

添加：

<context-param>
      <param-name>org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL</param-name>
      <param-value>true</param-value>
</context-param>

并在 jboss-deployment-structure.xml 中排除了JBoss的实现：

<jboss-deployment-structure>
    <deployment>

        <exclusions>
            <module name="javax.faces.api" />
        </exclusions>
             .
             .
             .

Answer 3

根据您的描述，您只使用正在使用的Eclipse和JBoss工具以及存储在Maven pom文件中的依赖项。要让Eclipse了解这些依赖关系，您需要进行eclipse-maven集成。 M2e是它的常见选择。

所以你需要安装这些：

m2e
m2e-wtp

Answer 4

转到pom.xml所在的目录并执行以下命令。

mvn package

此命令应创建一个war文件，供您部署到应用程序服务器。此文件是一个zip文件，查看其内容并查看myAuxiliaryStuff.jar是否在web-inf / lib中。如果是，你的问题在于eclipse与maven的集成。

Answer 5

您似乎安装了所有东西。我也有这个问题。只需右键单击项目并选择。

“标记为可部署”

使用依赖项从Eclipse部署Web应用程序到JBoss
