服务生成器给生命线带来错误7

Question

我在Liferay 7上工作。我是Liferay的新手，我遇到了一个我花费太多时间的问题。

我有一个portlet，我决定创建一个Service Builder（名为“Employee”）。这里是我的service.xml中：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 7.0.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_7_0_0.dtd"> 
<service-builder package-path="com.test"> 
    <author>sachin.singh</author> 
    <namespace>crud</namespace> 

    <entity name="Employee" table="user" local-service="true" remote-service="true"> 
     <column name="iduser" type="int" primary="true" id-type="increment"/> 
     <column name="name" type="String" /> 
     <column name="secret_code" type="String" /> 
    </entity> 
</service-builder> 

，当我使用Liferay的服务构建构建我在罐子库收到此错误

我检查和交叉核实，所有罐子在那里。

这里是加入的jar的截图：

Answer 1

尤其是当你是新手，我建议你再试一次，并使用Liferay的工作空间，而不是（不建议使用）插件-SDK的。所有样本（here's one for service builder）都基于此，plugins-sdk应主要用于将现有旧版插件迁移到最新版本。

我不确定你的屏幕截图显示了什么 - 如果它是所有捆绑的罐子，那么它看起来很可怕。在OSGi捆绑包中你应该只有很小的插件，并且它看起来像那些依赖关系太多了。
