该项目包含具有相同存档名称的另一个依赖项

标签： eclipse dependency-management m2e m2e-wtp

我在我的标记中看到以下错误（以及其他一些错误）：

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，我会在两个位置找到bcmail-jdk14.1.jar：

  • C：\用户\ LevineJ.m2 \库\ BouncyCastle的\ bcmail-JDK14 \ 138
  • C：\用户\ LevineJ.m2 \库\有机\ BouncyCastle的\ bcmail-JDK14 \ 1.38

从我对这个主题的阅读（各种帖子/文章），我认为这与我所看到的错误有关。有人可以提供一些信息： 1.这个错误是什么意思？ 2.我将如何解决它？

如果有帮助，我正在使用：

  • Eclipse Java EE - Luna Service Release 1（4.4.1）
  • m2e插件
  • m2e-wtp plugin

mvn dependency:tree

答案 0 :(得分：9)

问题是运行时*.jar依赖项已发布到WEB-APP/lib文件夹中。如果两个依赖项具有相同的名称，则无法发布它们。

您的问题很奇怪的是itext（及其bouncycastle依赖项）非常常见。我们公司的几个项目都有它，但我从未见过类似的警告。

Duplicate bouncycastle dependencies

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（因此具有不同的JAR名称）。所以问题必须在其他地方。

请检查 Java构建路径（或检查.classpath项目文件）设置和部署程序集设置。您必须手动无意中包含 bcmail 重复。

Deployment assembly settings

另外请确保您的src/main/webapp/WEB-INF/lib/中没有 bcmail-jdk14-1.38.jar 。

最后可能的怀疑可能是一些非传统的JBoss部署配置，将两个项目合并到一个Web应用程序中。但我并不熟悉JBoss Tools（只是猜测你是根据你的依赖关系使用它）。

答案 1 :(得分：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项目有不同的目录。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

答案 2 :(得分：1)

我遇到了这个问题，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>

答案 3 :(得分：0)

如果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，但是如果您在项目B中添加branchX，则会遇到此问题。
