Eclipse自动完成：Java 1.7通用钻石 [英] Eclipse Auto Complete: Java 1.7 Generics Diamond

问题描述

我刚刚升级到Luna（从开普勒），我注意到一些（但令人讨厌）的问题：

自动完成缺乏为变量中已经指定的泛型生成钻石的可能性初始化。例如，当我输入：

I just upgraded to Luna (from Kepler) and I noticed some little (yet annoying) problem:
The auto completion lacks the possibility to generate diamonds "<>" for already specified generics in variable initialisation. For Example, when I type:

Set<String> mySet = new HashSet 

我会期望，它自动完成到

I would expect, that it gets auto-completed to

Set<String> mySet = new HashSet<>();

而不是

Set<String> mySet = new HashSet<String>();

我正在使用JDK 1.7，合规级别也设置为1.7。

I am using JDK 1.7 and the compliance level is set to 1.7 also.

它也很奇怪，当我在自动完成期间多次击中STRG + Space，直到它再次达到java自动完成，然后按Enter输入预期的钻石。

Its also very strange that when I hit STRG+Space multiple times during auto-completing till it reaches java-autocompletion again and then hit Enter it delivers the expected diamonds.

这看起来很像我的错误。

这个错误是已知的，这个问题有什么解决方法吗？无法找到与此主题相关的任何内容。

This looks very much like a bug to me.
Is this bug "known" and is there any workaround for this issue? Could not find anything related to this topic.

推荐答案

您很可能安装了代码推荐器插件-在。不幸的是，此插件受到打破此功能的错误＃435597 的影响

You have most likely installed the Code Recommenders plug-in. Unfortunately this plug-in is affected by bug #435597 which breaks this functionality.

只有在默认的内容辅助列表中启用了某些提案类型 em>（Eclipse首选项> Java>编辑器>内容辅助>高级）。例如，我可以通过禁用以下提议类型来恢复正确的行为：

This bug appears to occur only if you have certain proposal kinds enabled in the "'default' content assist list" (Eclipse Preferences > Java > Editor > Content Assist > Advanced). For example I could get back the correct behavior by disabling the following proposal kinds:

• 基本提案


• JPA提案


• 模板提案

（最后一个可能是最烦人的，如果你正在使用代码模板...）

(the last one is likely the most annoying if you are using code templates…)

当您使用 ctrl + 空格骑车时，您实际上达到了 Java提案（而不是智能Java提案（代码推荐者）），这不会受到此错误的影响。

When you are cycling with ctrl+space, you are actually reaching the "Java Proposals" (instead of the "Intelligent Java Proposals (Code Recommenders)"), which is not affected by this bug.

此错误计划安装在版本2.2.0 在2015年6月。目前最好的方式是：

This bug is scheduled for release 2.2.0 in June 2015. The best you can do for the moment is:

• 建议，以检查哪些触发您的错误（可能在执行之前先获取当前设置的屏幕截图）;


• Vo te 针对错误＃435597 和 bug＃435660 以使其得到修正;


• <强>建议补丁修复这些错误： - ）

• Play with the proposals to check which ones trigger the bug for you (maybe take a screenshot of your current setup before doing that);
• Vote for bug #435597 and bug #435660 to get them fixed;
• Propose patches for fixing those bugs :-)
