Netbeans 8.0启动时出错

Question

我最近尝试安装https://blogs.oracle.com/geertjan/entry/python_in_netbeans_ide_8中描述的NetBeans插件

然而，当我现在尝试启动NetBeans时，我得到了一个可怕的错误，开始如下所示：

Warning - could not install some modules: Java Source Queries - None of the modules providing the capability org.netbeans.modules.java.source.queries.spi.QueriesController could be installed.

一页地继续。

我在OS上运行它。

我已经删除了目录/Users/<MyUser>/Library/Application Support/NetBeans和/Users/<MyUser>/Library/Caches/NetBeans，正如我在一些地方看到的那样，但我仍然收到相同的错误。

这完全削弱了我，阻止我做任何工作，我不知道发生了什么，也不知道如何解决它。

任何帮助都将受到极大的感谢。

Answer 1

在遇到同样的僵局后，我在netbeans.org和其他网站上来回搜索，并向bugs https://netbeans.org/bugzilla/show_bug.cgi?id=248986和https://netbeans.org/bugzilla/show_bug.cgi?id=248291#c5提供了我的日志

我穷追不舍地寻找。my %appdata%/Netbeans中的jar和xml文件，按最近修改时间排序，并找到如下文件：

C:\Users\master\AppData\Roaming\NetBeans\8.0\modules org-netbeans-modules-jira-rest.jar org-netbeans-modules-jira-xmlrpc.jar org-netbeans-modules-scanondemand.jar等等。

但是删除它们，或者用以前的版本替换它们，都没有帮助。

我发现没有真正的解决方案来回滚失败的更新，至少要让我的Netbeans重新启动，我在其他地方安装了每晚构建的http://bits.netbeans.org/download/trunk/nightly/latest/进行比较(在虚拟机上，我的“备用”PC上)。

继续将新安装与我的损坏安装进行比较。对我的损坏%appdata%的任何更改似乎都不允许NB启动。

最后，我比较了系统范围的安装文件夹，发现在我损坏的副本中，不仅许多.jar文件大小不同，而且有些文件完全丢失了，包括我收到的启动错误中广泛涉及的这个文件：

C:\ProgramFiles\NetBeans\platform\core\org-openide-filesystems-compat8.jar

这是最强烈的暗示，不会轻易有“修复”……

这就好像https://forums.netbeans.org/posting.php?mode=quote&p=79922中的一些源代码永远不应该被允许进入更新中心。( http://deadlock.netbeans.org/hudson/job/nbms-and-javadoc/lastStableBuild/artifact/nbbuild/nbms/updates.xml.gz在我的case....though中，依赖链是完全不清楚的。)

最后，我覆盖了整个C:\ProgramFiles\NetBeans\文件夹，从新安装到损坏的文件夹，并成功启动。

它需要一些更新，然后再重新启动。我的大多数设置仍然在那里，Dark主题，最近的文件列表，等等。除了Ruby on Rails插件，它仍然是禁用的，我仍然在尝试重新添加和启用它，因为它甚至阻止了我的ROR项目的打开。

因此，总而言之，这种糟糕的部分解决方法可能等同于使用开发版重新安装Netbeans (之前我使用的是8.0.2)。

Answer 2

请注意，您不应该将开发插件(如Python或Scan-on-Demand)安装到生产安装中。这样做很可能会破坏你的安装，你会很伤心。

如果要使用开发插件，请使用bits.netbeans.org/download/trunk/nightly/latest/提供的NetBeans 开发发行版

目前有一个专门针对IDE8.0.2的Geertjan Python插件；有关这方面的更多信息，请访问Geertjan的博客：https://blogs.oracle.com/geertjan/entry/python_in_netbeans_ide_81
