Question

我正在开发一个有多个子项目的maven项目，在子项目中，项目是weasis-core-ui，我添加了一些罐子，我想在项目中使用它。

我通过在weasis-core-ui的pom.xml中添加依赖项来实现这一点：以下代码包含依赖项，我正在使用的pom.xml

<dependency>
            <groupId>javax.xml.rpc</groupId>
            <artifactId>javax.xml.rpc</artifactId>
             <version>1.0.0</version>
            <scope>system</scope>
             <systemPath>E:/TestClient/WebContent/WEB-INF/lib/axis.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>Disc</groupId>
            <artifactId>Disc-Id</artifactId>
             <version>1.0.0</version>
            <scope>system</scope>
             <systemPath>E:/TestClient/WebContent/WEB-INF/lib/commons-discovery-0.2.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>JXRPC</groupId>
            <artifactId>JXRPC-Id</artifactId>
             <version>1.0.0</version>
            <scope>system</scope>
             <systemPath>E:/TestClient/WebContent/WEB-INF/lib/jaxrpc.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>SAAJ</groupId>
            <artifactId>SAAJ-Id</artifactId>
             <version>1.0.0</version>
            <scope>system</scope>
             <systemPath>E:/TestClient/WebContent/WEB-INF/lib/saaj.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>WSDL</groupId>
            <artifactId>WSDL-Id</artifactId>
             <version>1.0.0</version>
            <scope>system</scope>
             <systemPath>E:/TestClient/WebContent/WEB-INF/lib/wsdl4j.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>LOGGING</groupId>
            <artifactId>LOGGING-Id</artifactId>
             <version>1.0.0</version>
            <scope>system</scope>
             <systemPath>E:/TestClient/WebContent/WEB-INF/lib/commons-logging.jar</systemPath>
        </dependency>

清理项目，然后Maven测试，它工作正常。但是当我运行应用程序时，我遇到了这个例外。

Weasis cache will be cleaned at next launch.

请告诉我我做错了什么。感谢

如果我做得对，你已经将依赖项添加到weasis-core-ui并尝试从weasis-dicom-explorer访问它？

这通常是可能的，但被认为是不好的做法（因为它要求您导出不受您控制的包）。更好的方法是将weasis-core-ui的接口定义为尽可能少地依赖第三方数据类。然而，似乎即使它被正确配置它也不会起作用，因为weasis-core-ui也存在布线问题。当bundle在其MANIFEST.MF文件中找不到它声明为依赖的所有包时，会发生连接异常。在您的情况下＆＃34; javax.xml.rpc＆＃34;不见了。

现在发生的事情很乏味。您需要找出weasis-core-ui实际上需要javax.xml.rpc的原因。如果事实证明您的代码实际上没有使用需要此软件包的功能，那么您只需删除javax.xml.rpc的import package指令即可。如果您确实使用了需要此代码的代码，则需要找到导出该包的包或包含该包的jar - 例如Axis。

现在如何删除import语句在很大程度上取决于您如何管理MANIFEST.MF。如果您手动管理它，您只需删除该行，如果您通过maven-bundle-plugin管理它，则需要相应地更改您的pom以排除javax.xml.rpc。
