Question

我正在尝试从liferay 7.x门户运行我的6.2.5 portlet项目。

在运行环境下的项目构面中，Liferay 7.x服务器不可见。每当我尝试将war文件部署到Liferay 7.0 ce门户的部署文件夹中或者只是从liferay ide运行我的项目时，就会在javax.xml.parsers旁边抛出Hot deploymentexception：

您的Liferay Faces Bridge版本与Liferay 7不兼容。您应该使用Bridge API 4.x，Bridge Impl 4.x和Bridge Ext 5.x。由于尚未为Liferay 7发布Bridge，因此您需要使用SNAPSHOT builds。以下是 pom.xml 依赖项：

<dependency>
    <groupId>com.liferay.faces</groupId>
    <artifactId>com.liferay.faces.bridge.impl</artifactId>
    <version>4.0.0-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>com.liferay.faces</groupId>
    <artifactId>com.liferay.faces.bridge.api</artifactId>
    <version>4.0.0-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>com.liferay.faces</groupId>
    <artifactId>com.liferay.faces.bridge.ext</artifactId>
    <version>5.0.0-SNAPSHOT</version>
</dependency>

如果您有其他Liferay Faces依赖项，请查看the Liferay Faces version scheme以获取有关您应使用哪个版本的更多信息。
