Question

我有一个带有这些依赖项的maven（m2e eclipse）项目：

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>3.8.1</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-core</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-messaging-api</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-profile-api</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-saml-api</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-security-api</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-soap-api</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-storage-api</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-xmlsec-api</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>opensaml-saml-impl</artifactId>
        <version>3.3.0</version>
    </dependency>
    <dependency>
        <groupId>org.opensaml</groupId>
        <artifactId>xmltooling</artifactId>
        <version>1.4.6</version>
    </dependency>
</dependencies>

在Eclipse中运行mvn install -U，一切正常。

所以我使用Maven Dependency Plugin从依赖项中提取所有jar并在另一个项目中使用它们。

在本项目中，当我输入：

InitializationService.initialize();

我成了这个错误：

Exception in thread "main" java.lang.ClassCastException: org.opensaml.xml.signature.impl.CryptoBinaryBuilder cannot be cast to org.opensaml.core.xml.XMLObjectBuilder
at org.opensaml.core.xml.config.XMLConfigurator.initializeObjectProviders(XMLConfigurator.java:238)
at org.opensaml.core.xml.config.XMLConfigurator.load(XMLConfigurator.java:203)
at org.opensaml.core.xml.config.XMLConfigurator.load(XMLConfigurator.java:188)
at org.opensaml.core.xml.config.XMLConfigurator.load(XMLConfigurator.java:162)
at org.opensaml.core.xml.config.AbstractXMLObjectProviderInitializer.init(AbstractXMLObjectProviderInitializer.java:52)
at org.opensaml.core.config.InitializationService.initialize(InitializationService.java:56)

更新：我可以通过删除完整的maven存储库

来解决此问题

然后我使用Maven Assembly Plugin生成一个包含所有依赖项的jar。我可以传递InitializationService.initialize()罚款，但我在：

得到NullPointerException

marshaller = XMLObjectProviderRegistrySupport.getMarshallerFactory().getMarshaller(authnRequest.getElementQName());

Null从工厂返回。

相关：OpenSAML 3 unmarshaller is null

为什么我的程序在maven测试中运行时有效，但在我使用jar或带有dependend库的代码时却没有？

将Maven项目工作到jar或提取的opensaml 3依赖项将导致org.opensaml.core.xml.io.Marshaller为null
