storing, in a build environment repository, the collected information as a version of the build environment;

assigning a weigh to each of the one or more predefined build environment factors, wherein the assigned weigh is defined by a user according to a relevance of each of the one or more predefined build environment factors;

based on the assigned weigh being above a predefined weigh threshold, filtering the collected information such that only collected information corresponding to a predefined build environment factor having an assigned weigh higher than the predefined weigh threshold is stored;

storing, in the build environment repository, the filtered information; and

determining a difference between the filtered information and information corresponding to another build environment in which a previous build result was generated.

9. The computer system of claim 8 , further comprising:

storing, in the build environment repository, the difference between the filtered information and the information corresponding to another build environment as a version of the build environment, wherein a required storage space of the difference between the filtered information and the information corresponding to another build environment is less than a required storage space of a complete record of the filtered information.

10. The computer system of claim 8 , wherein filtering the collected information comprises:

obtaining information regarding at least one predefined build environment factor selected from the one or more predefined build environment factors.

11. The computer system of claim 8 , further comprising:

filtering the collected information based on at least one predefined build environment factor selected by the user via a user interface such that the filtered information comprises information regarding the at least one predefined build environment factor only.

12. The computer system of claim 8 , wherein the information corresponding to another build environment is obtained from the build environment repository.

13. The computer system of claim 8 , wherein the difference between the filtered information and the information corresponding to another build environment is stored as a list comprising one or more entries, each of which records a change in at least one of the one or more predefined build environment factors, and wherein at least one of the one or more entries comprises a recommendation for addressing a problem due to the change in the at least one of the one or more predefined build environment factors.

14. The computer system of claim 8 , wherein the one or more predefined build environment factors comprises at least one of a platform, an operating system, a patch of operating system, a compiler, a linker, a runtime of compiler, libraries used by compiler and linker, a hardware configuration of build machine, or preferences of build machine.

15. A computer program product comprising:

one or more computer readable storage media and program instructions stored on at least one of the one or more computer readable storage media, the program instructions executable by a computer to cause the computer to perform a method comprising:

receiving, by a computer, a build request for a source code;

in response to the received build request, generating a build result from the source code;

collecting information corresponding to a build environment, wherein the build result of the source code is generated in the build environment, the collected information comprising one or more predefined build environment factors;

storing, in a build environment repository, the collected information as a version of the build environment;

assigning a weigh to each of the one or more predefined build environment factors, wherein the assigned weigh is defined by a user according to a relevance of each of the one or more predefined build environment factors;
