Liferay生成服务失败

我已经为Liferay Service Builder创建了一个配置。在此之后，我尝试构建服务，但收到以下错误：

Buildfile: C:\LiferayNew\liferay-plugins-sdk-6.2\portlets\guestbook-portlet\build.xml

如何解决此问题？

您是否删除了文件

liferay-plugins-sdk-6.2\build.properties

或以任何方式对其进行了修改？不，我没有删除此文件。我是新来的，雷。现在，我删除了liferay-portal-6.2-ce-ga4和liferay-plugins-sdk-6.2以及liferay IDE。我创建了所有新的，然后我将创建一个新的portlet。检查build.properties中的ivy.jar.url。它应该以指定的协议（如http）开始。通常，它应该看起来像ivy.jar.url={ivy.version}/ivy-${ivy.version}.jarIn build..properties给出了ivy.jar.url的两个定义，注释中给出了一个定义#ivy.jar.url={ivy.version}/ivy-${ivy.version}.jar-ivy.jar.url={ivy.version}/org.apache.ivy-${ivy.version}.jar您是否删除了文件
