Using batch cmd: A quick way to find the jar file which includes the target class

Firstly, a simple example:

for %i in (dir/b/s *.jar) do 7z l %i | findstr XDatabase.class 

 

Result:

1. D:\shared\xsql>for %i in (dir/b/s *.jar) do 7z l %i |findstr XDatabase.class  
2.   
3. D:\shared\xsql>7z l dir/b/s   | findstr XDatabase.class  
4.   
5. D:\shared\xsql>7z l db2jcc.jar   | findstr XDatabase.class  
6.   
7. D:\shared\xsql>7z l db2jcc_license_cu.jar   | findstr XDatabase.class  
8.   
9. D:\shared\xsql>7z l jconn3.jar   | findstr XDatabase.class  
10.   
11. D:\shared\xsql>7z l jodbc.jar   | findstr XDatabase.class  
12.   
13. D:\shared\xsql>7z l jTDS3.jar   | findstr XDatabase.class  
14.   
15. D:\shared\xsql>7z l mlscript.jar   | findstr XDatabase.class  
16.   
17. D:\shared\xsql>7z l msbase.jar   | findstr XDatabase.class  
18.   
19. D:\shared\xsql>7z l mssqlserver.jar   | findstr XDatabase.class  
20.   
21. D:\shared\xsql>7z l msutil.jar   | findstr XDatabase.class  
22.   
23. D:\shared\xsql>7z l mysql-connector-java-5.1.6-bin.jar   | findstr XDatabase.class  
24.   
25. D:\shared\xsql>7z l ojdbc14.jar   | findstr XDatabase.class  
26.   
27. D:\shared\xsql>7z l postgresql-8.4-701.jdbc4.jar   | findstr XDatabase.class  
28.   
29. D:\shared\xsql>7z l sqlite.jar   | findstr XDatabase.class

Summary:

We can write a batch cmd, together with 7z.exe, 7z.dll, like:

1. @echo off  
2. SETLOCAL  
3.   
4. set WHICH_CLASS=%1  
5. echo WHICH_CLASS=%WHICH_CLASS%  
6.   
7. for /F %%i in ('dir /A:-D /S /B *.jar') do 7z l %%i | findstr %WHICH_CLASS% && echo %WHICH_CLASS% found in: "%%i"  
8. echo "Finished class finding..."  
9. echo "======================================"  
10. ENDLOCAL  

 

See an example:

findclass com\\sybase\\afx\\util\\StringUtil.class 
WHICH_CLASS=com\\sybase\\afx\\util\\StringUtil.class 
2012-02-27 13:14:36 .....        15230         5915  com\sybase\afx\util\StringUtil.class 
com\\sybase\\afx\\util\\StringUtil.class found in: "U:\target\lib\ext\sup-client.jar" 
2012-02-27 13:14:36 .....        15230         5915  com\sybase\afx\util\StringUtil.class 
com\\sybase\\afx\\util\\StringUtil.class found in: "U:\target\lib\ext\sup-server-rt.jar" 
"Finished class finding..." 
"======================================"

 

If you are interested in the source code of 7-zip, you can modify the source code and make it output the source file path when using

7z l <%%i> | findstr .....

 

It's very useful in your java project or java diagnostics work.
