1. A method for obtaining context information for a software development task, the method comprising: finding, by a processor, in response to designating any one tool component associated with the software development task as a root component, at least one other tool component having an at least one-level link with the root component; extracting, by the processor, context information from the root component and the at least one other tool component; and generating, by the processor, a context set based on the extracted context information, the generating comprising: establishing a context entry for each piece of the extracted context information, wherein the context entry comprises the corresponding context information; creating an index for the context entry; generating a context set based on the context entry and the index; assigning an identifier to the context set; and associating the indexes of the context entries in the context set with the identifier of the context set, and outputting the context set to a user; and finding other tool components where the number of levels of the link between which and the root component does not exceed a predetermined threshold.
