Write the batch file bat

One, a command window that defines a time title

@echo off
: 1
Title Time is:%time%
Goto 1
Pause

Two, determine whether two input characters are equal

@echo off
set/p var= Please enter the first character:
set/p var2= Please enter a second character:
If "%var%" = = "%var2%" (echo US equals) Else echo we're not equal
Pause

Third, compile the Java file

1)
@echo off
CD E:\jenkinsTest

javac-d E:\JENKINSTEST\ZCD\CLASSZCD Testjavac.java
CD E:\JENKINSTEST\ZCD\CLASSZCD
Java Coms.zcd.action.TestJavac

mkdir Practice2
IF%errorlevel%==0 ECHO Success
IF%errorlevel%==1 ECHO fail

: End
Pause

=========
2)
@echo off
CD E:\jenkinsTest

javac-d. \ZCD\CLASSZCD Testjavac.java
CD E:\JENKINSTEST\ZCD\CLASSZCD
Java Coms.zcd.action.TestJavac

mkdir Practice2
IF%errorlevel%==0 ECHO Success
IF%errorlevel%==1 ECHO fail

: End
Pause

===========
3)
@echo off
CD E:\jenkinsTest

javac-d. \ZCD\CLASSZCD Testjavac.java
CD. \ZCD\CLASSZCD
Java Coms.zcd.action.TestJavac

mkdir Practice2
IF%errorlevel%==0 ECHO Success
IF%errorlevel%==1 ECHO fail

: End
Pause
===================================

4)
@echo off
CD E:\jenkinsTest
javac-d. \zcd\classzcd-classpath Lib-djava.ext.dirs=e:\jenkinstest\lib Testjavac.java
CD. \ZCD\CLASSZCD
Java Coms.zcd.action.TestJavac
mkdir Practice2
IF%errorlevel%==0 ECHO Success
IF%errorlevel%==1 ECHO fail
: End
Pause

where javac-d. \zcd\classzcd-classpath lib-djava.ext.dirs=e:\jenkinstest\lib Testjavac.java means compiling Testjavac.java files, and the resulting class file into the current directory subdirectory CLASSZCD directory, and the Java file in the package name to create a corresponding folder,-classpath Lib-djava.ext.dirs=e:\jenkinstest\lib Represents the Testjavac.java dependency E:\jenkinsTest\lib the following package
==============================
5) Compile the current directory all Java files in the subdirectory src
@echo off
CD E:\jenkinsTest
javac-d. \zcd\classzcd-classpath lib-djava.ext.dirs=e:\jenkinstest\lib. \src\*.java
CD. \ZCD\CLASSZCD
Java Coms.zcd.action.TestJavac
mkdir Practice2
IF%errorlevel%==0 ECHO Success
IF%errorlevel%==1 ECHO fail
: End
Pause
