该项目包含另一个具有相同存档名称的依赖项

Question

我在我的标记中看到以下错误（以及其他几个类似的错误）：

Invalid classpath publish/export dependency C:/Users/LevineJ/.m2/repository/org/bouncycastle/bcmail-jdk14/1.38/bcmail-jdk14-1.38.jar.
The project contains another dependency with the same archive name.

当我进行快速搜索时，我在两个位置找到了bcmail-jdk14.1.jar：

• C:\Users\LevineJ.m2\repository\bouncycastle\bcmail-jdk14\138
• C:\Users\LevineJ.m2\repository\org\bouncycastle\bcmail-jdk14\1.38

根据我阅读的有关该主题的内容（各种帖子/文章），我认为这与我看到的错误有关。有人可以提供一些关于： 1.这个错误是什么意思？ 2. 我该如何解决？

如果有帮助，我正在使用：

• Eclipse Java EE - Luna 服务版本 1 (4.4.1)
• m2e 插件
• m2e-wtp 插件

Maven 依赖项/构建路径的屏幕截图

部署程序集的屏幕截图 谢谢。

Answer 1

问题是运行时 *.jar 依赖项已发布到 WEB-APP/lib 文件夹中。如果两个依赖同名，则无法发布。

您的问题的奇怪之处在于itext（及其bouncycastle 依赖项）非常普遍。我们公司的几个项目都有，但我从未见过类似的警告。

所以这让我想知道问题出在哪里。两个重复的依赖项（bcmail 和 bcprov）实际上并不重复 - 它们有不同的版本（因此 JAR 名称不同）。所以问题一定出在其他地方。

请检查您的Java 构建路径（或检查.classpath 项目文件）设置和部署程序集 设置。您必须手动包含无意中包含的 bcmail 副本。

还要确保您的 src/main/webapp/WEB-INF/lib/ 中没有 bcmail-jdk14-1.38.jar。

最后一个可能的嫌疑人可能是将两个项目组合到一个 Web 应用程序中的一些非常规的 JBoss 部署配置。但是我对 JBoss Tools 不是很熟悉（只是根据依赖项猜测您正在使用它）。

Answer 2

我已经检查了上面的所有答案，但它们对我不起作用。我发现我的 Maven 项目与常规 Java Web 项目的目录不同。我检查了根目录中的文件 .classpath 并更改了

<attributes>
        <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
</attributes>

到

<attributes>
        <attribute name="org.eclipse.jst.component.dependency" value="**WebRoot**/WEB-INF/lib"/>
</attributes>

解决了我的问题

Answer 3

我遇到这个问题是因为我有以下配置

           <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <outputFileNameMapping>@{artifactId}@.@{extension}@</outputFileNameMapping>
                </configuration>
            </plugin>

当我将@version@ ​​添加到 outputFileNameMapping 时，它解决了这个错误。

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <outputFileNameMapping>@{artifactId}@.@{extension}@.@{version}@</outputFileNameMapping>
                </configuration>
            </plugin>

Answer 4

如果您在工作区中加载同一项目（依赖项目）的另一个副本，也会发生这种情况。项目A依赖于项目B，但是如果你在项目B的branchX中添加，那么你就会遇到这个问题。
