在Eclipse中，如何使用“Workspace…”语法(例如，${workspace_loc:/myworkspace})指定一个文件(用于控制台日志)?

I was following the instructions in this answer: View deleted console output

我按照这个答案中的说明:查看已删除的控制台输出

(to set up a file in which Eclipse will record everything that goes to the console _{(too bad that is not done by default!)}), and under:

(建立一个文件，Eclipse将在其中记录所有进入控制台的内容(太糟糕了，默认情况下没有这么做!)

there are 3 options

有三个选项

Workspace...
工作空间……
File System...
文件系统……
Variables...
变量……

I wanted to use "Workspace...", and I selected my workspace, which generated text like this in the text box:

我想用“工作区…”，我选择了我的工作空间，它在文本框中生成这样的文本:

${workspace_loc:/myworkspacesubfolder}

$ { workspace_loc:/ myworkspacesubfolder }

I wanted to specify the file name, and I tried all of these forms:

我想指定文件名，我尝试了所有这些表单:

${workspace_loc:/myworkspacesubfolder}test.txt

$ { workspace_loc:/ myworkspacesubfolder }用法

${workspace_loc:/myworkspacesubfolder}/test.txt

$ { workspace_loc:/ myworkspacesubfolder } /用法

${workspace_loc:/myworkspacesubfolder}\test.txt

$ { workspace_loc:/ myworkspacesubfolder } \用法

...but none of them worked. (No errors alerts were thrown, but neither was the text file generated upon running the program.)

…但他们都没有成功。(没有抛出错误警报，但在运行程序时也没有生成文本文件。)

_{(I then gave up and used "File System..." instead of "Workspace...", which takes a standard path such as}

(然后我放弃使用“文件系统…”而不是“工作区…”，它采用标准路径，例如

C:\test.txt

C:\用法

^{, but...)}

,但是……)

What is the proper syntax for using "Workspace..."?

使用“工作区…”的正确语法是什么?

2 个解决方案

#1

The proper syntax for this is: ${workspace_loc:/myworkspacesubfolder/test.txt} Make sure that you manually create test.txt file in that location. I is not created automatically by eclipse.

正确的语法是:${workspace_loc:/myworkspacesubfolder/test。确保您手动创建了测试。在那个位置的txt文件。我不是由eclipse自动创建的。

#2

The correct syntax is ${workspace_loc:/myworkspacesubfolder}/test.txt. This works even when the file does not already exist.

正确的语法是${workspace_loc:/myworkspacesubfolder}/test.txt。即使这个文件不存在，它也可以工作。

See this Eclipse bug for an explanation of why ${workspace_loc:/myworkspacesubfolder/test.txt} doesn't work when the file doesn't already exist.

有关${workspace_loc:/myworkspacesubfolder/test的解释，请参见这个Eclipse bug。当文件不存在时，txt}不能工作。
