无法创建新的AWS java web项目

Question

我在OSX 10.8.2下使用Eclipse 4.2.1。

在Eclipse > Preferences > Java > installed JRE中，我已经安装了JavaSE6。

我从Eclipse Marketplace安装了Amazon AWS SDK。

我正在尝试启动一个新的AWS Java Web项目，但收到以下错误：

Unable to create new AWS Java web project.
One or more constraints have not been satisfied.
Dynamic Web Module 2.5 require Java 1.5 or newer.

但是我用的是Java SE 1.6！为什么？

有什么想法吗？

Answer 1

我安装了Eclipse for Java EE，而不是Eclipse generic，它解决了这个问题。

Answer 2

我在Windows8.1专业版上遇到了类似的问题。我尝试了很多方法，但在移除所有现有的ElasticBeanstalk版本并安装JavaEE7u45 win32 (之前是JEE8，均为32和64位)之前，我无法成功地将任何东西部署到AWS。

但这是我所做的全部：

• 删除了现有工作区并创建了一个新工作区。
• 确保正确设置了您的AWS工具包首选项: Window ->首选项和AWS Toolkit
• Removed所有现有版本的java.
• Downloaded并安装了

EE 7u45 win32。

• 确保正确设置了我的系统路径和JAVA_HOME变量:控制面板->系统和安全-> System ->高级系统设置->高级->环境变量

希望这能有所帮助:)

我安装了Eclipse4.3.2，然后在顶部添加了AWS，我得到了同样的错误。与在Java 1.7.0_51或Java8 (b132)上运行Eclipse相同。

我还收到一个错误对话框，提示"X不存在“，其中X是我的新项目名称。创建了X，但在.settings中只有一个.project文件和一个文件。

我的错误日志包含：

Dynamic Web Module 2.5需要Java 1.5或更高版本。
