Recently, I have made a project. After I finished, I found a problem, and the Class file compiled with Ant is different from the file size compiled by JB. So I guess that the compiler used by JB is not Javac. So start to query some information. Finally, it is found to be like this.
The compiler used in JB compiles projects can be selected, which own with a BMJ (Borland make For Java), BCJ (Borland Compile for Java). When doing projects, you can choose to use JB8 compilers or use Javac or other.
BMJ is mainly to improve the efficiency of compilation. Because JB is created when the file is created, it will establish a time-identified file. When compiled with BMJ, it will first detect the part of the file being modified, and then only compile the part, which greatly reduces the compilation time.
In addition, JB can also compile, build an operation, etc. by command line.
