Maven-如何從生成的JAR中排除依賴項

Question

我有3個看起來像這樣的項目：

問題在於，常見的DB代碼具有轉換器類，並且在運行業務邏輯時出現以下錯誤。

Caused by: org.hibernate.AssertionFailure: AttributeConverter class [class com.td.sba.iep.jpa.converters.ModeltoDBAttributeConverter] registered multiple times

我做了什么：在使用pom.xml中的以下代碼打包Utility類時，我試圖排除依賴項。

            <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <!-- Fools the plugin into creating the code only jar instead of the runnable one -->
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <classifier>exec</classifier>
                    </configuration>
                </execution>
            </executions>
        </plugin> 

但是，當我將創建的exec jar包含到業務邏輯中時，它表明未找到實用程序類。

我需要：如何解決“ org.hibernate.AssertionFailure”？ 從實用程序類創建jar時應該排除依賴項嗎？ 我該怎么做？

萬一重要，我正在使用Eclipse。

Answer 1

您是否嘗試過在此項目依賴項上使用<exclusions>元素？ 喜歡：

業務邏輯項目pom.xml文件：

    <dependency>
        <groupId>com.utility.project</groupId>
        <artifactId>UtilityProject</artifactId>
        <version>1.0.0</version>
        <exclusions>
            <exclusion>
                <groupId>group.id.jar.you.want.to.exclude</groupId>
                <artifactId>artifact.id.jar.you.want.to.exclude</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

UPDATE

由於您的UtilityProject pom已經具有CommonDB依賴關系，因此請從業務邏輯pom中刪除此CommonDB依賴關系。 此錯誤是因為您有2個類（相同的類）被注冊了相同的名稱。 如果您已經對UtilityProject擁有CommonDB依賴關系，並且將該UtilityProject用作對Business的依賴關系，則無需將其導入兩次。
