eclipse 该项目包含另一个具有相同存档名称的依赖项

The project contains another dependency with the same archive name

提问by Jeff Levine

I'm seeing the following error (and a couple of others like it) in my markers:

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.

When I do a quick search, I find bcmail-jdk14.1.jarin two locations:

当我进行快速搜索时，我bcmail-jdk14.1.jar在两个位置找到：

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

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

From what I've read on the topic (various posts/articles), I'm thinking this has to do with the error I'm seeing. Can someone please provide some info regarding: 1. What does this error mean? 2. How would I go about solving it?

从我读到的有关该主题的内容（各种帖子/文章）来看，我认为这与我看到的错误有关。有人可以提供一些关于以下方面的信息： 1. 这个错误是什么意思？2. 我将如何解决它？

If it helps, I'm using:

The issue is that runtime *.jardependencies are published into WEB-APP/libfolder. If two dependencies have the same name, they can not be published.

问题是运行时*.jar依赖项被发布到WEB-APP/lib文件夹中。如果两个依赖同名，则不能发布。

The strange thing with your issue is that itext(with its bouncycastledependencies) are pretty common. Several projects in our company have it, but I have never seen a similar warning.

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，但是我从来没有看到过类似的警告。

So this makes me wonder, where the issue comes from. The two duplicate dependencies (bcmailand bcprov) are actually not duplicate - they have different version(hence different JAR name). So the issue must be somewhere else.

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

Please check your Java Build Path(or check .classpathproject file) settings and Deployment Assemblysettings. You must have unintentionally included bcmailduplicate manually.

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。您必须无意中手动包含了bcmail副本。

Also make sure you don't have bcmail-jdk14-1.38.jarin your src/main/webapp/WEB-INF/lib/.

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

And last possible suspect might be some unconventional JBoss deployment configuration combining two projects into one web application. But I am not that familiar with JBoss Tools (just guessing you are using it based on your dependencies).

最后一个可能的怀疑可能是一些非常规的 JBoss 部署配置，将两个项目合并到一个 Web 应用程序中。但是我对 JBoss Tools 不太熟悉（只是根据您的依赖关系猜测您正在使用它）。

I've checked all answers above but they don't work for me. I found that my Maven project has a different directory than regular Java Web project. I checked file .classpath in root directory and I changed

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>

to

到

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

which solved my problem

这解决了我的问题

I was getting this issue because I was having following configuration

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>

When I added @version@ to outputFileNameMapping, it resolved this error.

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>
