mvn clean package 仅使用 META-INF 构建 EAR答案

【问题标题】：mvn clean package builds EAR with only META-INFmvn clean package 仅使用 META-INF 构建 EAR
【发布时间】：2015-02-04 01:20:05
【问题描述】：

我正在尝试构建一个要在 WebLogic 上运行的项目（打包为一个耳朵）。然而，虽然构建（mvn clean package）成功，但ear文件只包含一个META-INF文件夹，里面的文件很少。

我对这个项目（或 EJB）不是很熟悉，但它看起来像一个 EJB 项目（我看到了 EJBHome、EJBObject、EJBLocalObject）。

不太确定从这里去哪里 - 我已经在网上和其他帖子中搜索过，但没有找到太多内容。即使是正确方向的一点也会很有用。

【问题讨论】：

显示项目 pom.xml
@sunysen - 刚刚添加了构建和源 pom.xml 文件。

标签： java build ejb maven-3 ear

【解决方案1】：

我认为问题在于您的 ejb 打包 jar 没有依赖项..

查看以下 GitHub 存储库： https://github.com/StefanHeimberg/stackoverflow-1134894

在那里你可以看到一个简单的例子，你应该如何用 maven 打包一个 java ee 应用程序。

ear 项目的 pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>com.example.myproject</groupId>
        <artifactId>parent</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <artifactId>myproject-application</artifactId>
    <packaging>ear</packaging>

    <name>MyProject - Application</name>

    <dependencies>
        <dependency>
            <groupId>com.example.myproject</groupId>
            <artifactId>myproject-web</artifactId>
            <type>war</type>
        </dependency>

        <dependency>
            <groupId>com.example.myproject</groupId>
            <artifactId>myproject-business</artifactId>
            <type>ejb</type>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <artifactId>maven-ear-plugin</artifactId>
                <configuration>
                    <modules>
                        <webModule>
                            <groupId>com.example.myproject</groupId>
                            <artifactId>myproject-web</artifactId>
                        </webModule>
                        <ejbModule>
                            <groupId>com.example.myproject</groupId>
                            <artifactId>myproject-business</artifactId>
                        </ejbModule>
                    </modules>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

父 pom.xml 中的属性：

<maven.ear.duplicateArtifactsBreakTheBuild>true</maven.ear.duplicateArtifactsBreakTheBuild>
<maven-ear-plugin.version>2.10</maven-ear-plugin.version>

您的父 pom.xml 部分中的 EAR 插件配置：

<plugin>
    <artifactId>maven-ear-plugin</artifactId>
    <version>${maven-ear-plugin.version}</version>
    <configuration>
        <fileNameMapping>no-version</fileNameMapping>
        <version>7</version>
        <!-- Die EAR Spezifikation sieht den *.ear/lib ordner als standard vor.
        dieser muss im application.xml nicht zusätzlich aufgelistet werden. -->
        <defaultLibBundleDir>lib</defaultLibBundleDir>
        <libraryDirectoryMode>NONE</libraryDirectoryMode>
    </configuration>
</plugin>
