Eclipse不在Package Explorer中显示项目

[英]Eclipse doesn't show projects in package explorer

原文 2014-08-22 12:59:43 6 4 java/ eclipse

I keep my workspace folder in the Dropbox folder so I can use it on different computers. 我将工作区文件夹保留在Dropbox文件夹中，以便可以在其他计算机上使用它。 Usually there isn't a problem. 通常没有问题。 Today however I opened Eclipse and found it doesn't show the projects in the package explorer. 但是，今天我打开了Eclipse，发现它没有在包资源管理器中显示项目。

I checked and it's set to the correct workspace folder. 我检查了一下，并将其设置为正确的工作区文件夹。

I tried to Import existing projects into workspace , but Eclipse doesn't allow importing the projects because 'they already exist in the workspace' - even though they don't appear. 我试图将Import existing projects into workspace ，但是Eclipse不允许导入项目，因为“它们已经存在于工作区中”-即使它们没有出现。

Will appreciate your help. 将感谢您的帮助。

4 个解决方案

Keep your project files in DropBox. 将项目文件保存在DropBox中。 You shouldn't share a workspace like that -- it will inevitably lead to issues like the one you describe. 您不应该共享这样的工作空间-它将不可避免地导致出现您所描述的问题。

That is, keep the project folder, along with the .project, .classpath, and .settings/ in your shared Dropbox space. 也就是说，将项目文件夹以及.project，.classpath和.settings /保留在共享的Dropbox空间中。 Create a new workspace on each computer, then "Import existing project" into each workspace, selecting your project in Dropbox, being sure to unselect "copy projects into workspace". 在每台计算机上创建一个新的工作区，然后将“导入现有项目”导入每个工作区，在Dropbox中选择您的项目，确保取消选择“将项目复制到工作区”。

I don't have idea about using dropBox - BUT - However 我没有关于使用Dropbox的想法 - 可是 -

For your question :: 您的问题 ::

I tried to Import existing projects into workspace, but Eclipse doesn't allow importing the projects because 'they already exist in the workspace' - even though they don't appear.

Possibility :: Projects are not in Eclipse explorer but a copy of it exists in the workspace folder so eclipse is not allowing you to add the projects with same name again. 可能性 ::项目不在Eclipse Explorer中，但是workspace文件夹中存在项目的副本，因此eclipse不允许您再次添加具有相同名称的项目。

Solution :: Create a new workspace and then use dropbox to import the projects. 解决方案 ::创建一个新的workspace ，然后使用dropbox导入项目。

What you can also try is do 您还可以尝试的是

Create new General Project 建立新的一般专案
Select in current workspace 在当前工作空间中选择
Create project with name of an already existing project in your workspace 使用工作空间中现有项目的名称创建项目

I seem to remember using this to "hydrate" already existing projects in my workspace into the eclipse package explorer. 我似乎记得使用此工具将工作区中已经存在的项目“混合”到eclipse包资源管理器中。

This happened to me and it was because I inadvertently filtered out some of the files in the filters option in the Package Explorer. 这发生在我身上，是因为我无意中滤除了程序包资源管理器中filter选项中的某些文件。

Inside PackageExplorer -> Small drop down on top right side -> Filters 内部PackageExplorer->右上方的小下拉菜单->过滤器

Un-select all and see if your files are now visible. 取消全选，然后查看您的文件现在是否可见。 Worked for me. 为我工作。
