爲什麼git不要忽略maven目標文件夾中surefire-reports \文件夾的內容？

Question

Git正確地忽略了我的目標文件夾（maven）中除文件夾「surefire-reports」以外的所有內容。

我的.gitignore：

# Java 
*.class 
.idea/ 

# Package Files 
*.jar 
*.war 
*.iml 
*.ucls 
target/ 

但文件的目標\萬無一失的報告\仍git的跟蹤。看到git狀態輸出：

# On branch connectionPane 
# Changes not staged for commit: 
# (use "git add <file>..." to update what will be committed) 
# (use "git checkout -- <file>..." to discard changes in working directory) 
# 
# modified: target/surefire-reports/TEST-navalwar.ConsolePlayerTest.xml 
# modified: target/surefire-reports/navalwar.ConsolePlayerTest.txt 
# 
# Untracked files: 
# (use "git add <file>..." to include in what will be committed) 
# 
# gitstatus.txt 
no changes added to commit (use "git add" and/or "git commit -a") 

還有其他文件夾和文件在目標\但git不跟蹤它們！

如果這些文件先前已經簽入git，git仍然會關注它們，即使它們符合忽略標準。因爲它們已被修改，我們知道他們已經在先前檢查

在這裏看到：How to make Git "forget" about a file that was tracked but is now in .gitignore?和Ignoring an already checked-in directory's contents?

簡短的回答：這將做的工作，而不是刪除本地文件：

git rm -r --cached <your directory>
