问题描述
(旧问题凸点)
我正在Liferay上进行一些测试.为此，我遵循了MVC教程，并陷入了服务方面.
I'm doing some tests on Liferay. For this, I'm following the MVC tutorial, and got stuck in the services stuff.
我创建了一个用于测试目的的简单实体"Miclase":
I created a simple entity for testing purposes, "Miclase":
public class Miclase {
int num1;
String string1;
}
非常简单，呵呵.好吧，此后，我启动了服务构建器，并使用概述"窗格创建了一个像这样的文件:
Pretty simple, huh. Well, after this, I started the service builder and created a file like this, with the Overview pane:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.2.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_2_0.dtd">
<service-builder package-path="asd">
<author>hp</author>
<namespace>Miservicio</namespace>
<entity name="Miclase" local-service="true">
<column name="num1" type="int" primary="false"></column>
<column name="string1" type="String"></column>
<!-- PK fields -->
<column name="miclaseId" type="long" primary="true"></column>
<!-- Group instance -->
<column name="groupId" type="long"></column>
<!-- Audit fields -->
<column name="companyId" type="long"></column>
<column name="userId" type="long"></column>
<column name="userName" type="String"></column>
<column name="createDate" type="Date"></column>
<column name="modifiedDate" type="Date"></column>
<finder name="GroupId" return-type="Collection">
<finder-column name="groupId"></finder-column>
</finder>
</entity>
</service-builder>
概述"窗格中的所有内容均显示无误，因此我单击了构建服务"按钮，它创建了许多源代码:
Everything showed up without errors in the "Overview" pane, so I clicked the "Build service" button, it created a lot of source code:

但是...在之前的输出之后，我得到以下构建失败:
but... after the previous output, I get the following build fails:

我在这里做错了吗?
推荐答案
我有同样的错误，并且已经解决了6个小时！
I had the same mistake and I've been solving it for 6 hours!
该解决方案非常简单:
您需要进入Window - Preferences - Server - Runtime Environments，选择您的环境，按edit，然后选择JDK 1.7.0_79，但不 1.8.x..不同版本存在问题.
You need to go Window - Preferences - Server - Runtime Environments, choose your environment, press edit, and then choose JDK 1.7.0_79, but NOT 1.8.x.. There is a problem in different versions.
我希望它将为某人节省大量时间. :D
I hope it will save someone a plenty of time. :D
