构建libgdx新Gradle项目模型时出现错误

Question

我在eclipse中安装了Gradle，并想导入一个libgdx Gradle项目。但当我点击“构建模型”按钮时，在加载栏的约50%处出现错误。以下是问题：

我在尝试导入或创建新的gradle项目时遇到了相同的问题。我注意到这个问题很近期，而且它发生在我刚刚进行了eclipse更新之后。也许这个更新有关？无论如何，这与libgdx无关。 - Elias Vasylenko

遇到了一些麻烦，无法正确地还原...但似乎与最近的更新有关，正如我们所怀疑的那样。昨天在这里提出了一个问题，并已被几个人确认：https://github.com/spring-projects/eclipse-integration-gradle/issues/48 - Elias Vasylenko

我也在STS中创建了一个问题：https://issuetracker.springsource.com/browse/STS-3922 - Elias Vasylenko

Answer 1

感谢 Kris De Volder 和 'Alex' 提供以下解释和解决方法，他们在我在此地址打开的问题上进行了评论：https://issuetracker.springsource.com/browse/STS-3922，这里主要是直接引用他们的话来为此问题提供完整答案:

"这个问题源于以下系统属性[...因为它们包含]不可序列化的值。这些属性是：

osgi.configuration.area.default
osgi.user.area.default
osgi.user.area

作为一种解决方法，人们可以将-D属性添加到他们的STS.ini、eclipse.ini或GGTS.ini中，将这些属性设置为它们在Eclipse 4.4.1中曾经拥有的值。

-Dosgi.configuration.area.default=null
-Dosgi.user.area.default=null
-Dosgi.user.area=@user.dir

"我们还将在即将发布的Gradle 3.6.2版本的工具中添加此解决方法，这样当安装gradle插件时，这些属性将自动添加到.ini文件中。

值得一提的是，Gradle似乎也已经在他们的端口修复了这个问题，因此另一个解决方法是使用Gradle 2.2.BUILD-SNAPSHOT。通过工具中的Gradle首选项页面或在gradle项目中的gradle.wrapper中设置它。

现在你已经掌握了一个简单的修复方法，可以手动应用，也可以通过更新来实现。我可以确认它能够解决问题。

"

这是我对在Eclipse中使用Gradle的第一印象。我现在感到有点困惑，但感谢您的修复。它有效了。 - Thomas Uhrig

NotSerializableException: org.eclipse.osgi.internal.framework.EquinoxConfiguration$1 java.lang.reflect.InvocationTargetException我在最新的3.6.1版本中仍然遇到这个错误... :( 我添加了上面的行，它们在后面吗？ - Marcello DeSales

Answer 2

我认为在STS的安装目录下有一个/configuration/config.ini文件时，编辑当前答案会更容易些。

正确编辑config.ini的格式略有不同，因为你不需要在属性前面添加“-D”。

应该是这样：

osgi.configuration.area.default=null
osgi.user.area.default=null
osgi.user.area=@user.dir

- Ash

谢谢@Ash...这对我有用！！！我已经对上面的答案感到沮丧了。 - Marcello DeSales

Answer 3

我也遇到了同样的问题，以下是我是如何解决的。首先，这很容易。

[按照以下3个步骤操作]
第一步：连接到互联网，然后单击“构建模型”。
第二步：它将开始下载一个zip文件。
第三步：之后重新启动eclipse。

享受编码... :)
