Generating rules for migrating dependencies of a software application

a processor; and

a memory including instructions that are executable by the processor for causing the processor to:

receive a source version of a dependency of a software application and a target version of the dependency of the software application, the dependency being used by the software application to perform one or more tasks of the software application;

compare the source version of the dependency to the target version of the dependency to determine a difference between the source version of the dependency and the target version of the dependency;

receive a template for a rule indicating a location in the source version of the dependency to be modified for the software application to support the target version of the dependency, the template including a fillable section;

populate the fillable section of the template with a value based on the difference between the source version of the dependency and the target version of the dependency; and

output a report including the rule and a modification for the source version of the dependency for the software application to support the target version of the dependency.

2. The system of claim 1 , wherein the memory further includes instructions that are executable by the processor for causing the processor to:

determine a plurality of differences between the source version of the dependency and the target version of the dependency;

classify each difference of the plurality of differences based on a severity of the difference;

filter the plurality of differences into a subset of differences, the severity of each difference in the subset of differences being above a threshold; and

generate, for each difference of the subset of differences, the rule by populating the fillable section of the template based on the difference.

3. The system of claim 1 , wherein the memory further includes instructions that are executable by the processor for causing the processor to select the template from a plurality of templates based on the difference between the source version of the dependency and the target version of the dependency.

4. The system of claim 1 , wherein the memory further includes instructions that are executable by the processor for causing the processor to store the rule in a repository of rules subsequent to populating the fillable section of the template.

5. The system of claim 1 , wherein the memory further includes instructions that are executable by the processor for causing the processor to generate a test for the rule by:

subsequent to populating the fillable section of the template, receiving a test template for the rule, the test template including an additional fillable section; and

populating the additional fillable section based on the rule.

6. The system of claim 5 , wherein the memory further includes instructions that are executable by the processor for causing the processor to store the rule and the test for the rule in a repository.

7. The system of claim 1 , wherein the difference comprises semantic information about the source version of the dependency and the target version of the dependency.

8. A method comprising:

receiving a source version of a dependency of a software application and a target version of the dependency of the software application, the dependency being used by the software application to perform one or more tasks of the software application;

comparing the source version of the dependency to the target version of the dependency to determine a difference between the source version of the dependency and the target version of the dependency;

receiving a template for a rule indicating a location in the source version of the dependency to be modified for the software application to support the target version of the dependency, the template including a fillable section;

populating the fillable section of the template with a value based on the difference between the source version of the dependency and the target version of the dependency; and

outputting a report including the rule and a modification for the source version of the dependency for the software application to support the target version of the dependency.

9. The method of claim 8 , further comprising:

determining a plurality of differences between the source version of the dependency and the target version of the dependency;

classifying each difference of the plurality of differences based on a severity of the difference;

filtering the plurality of differences into a subset of differences, the severity of each difference in the subset of differences being above a threshold; and

generating, for each difference of the subset of differences, the rule by populating the fillable section of the template based on the difference.

10. The method of claim 8 , further comprising:

selecting the template from a plurality of templates based on the difference between the source version of the dependency and the target version of the dependency.

11. The method of claim 8 , further comprising:

storing the rule in a repository of rules subsequent to populating the fillable section of the template.

12. The method of claim 8 , further comprising generate a test for the rule by:

subsequent to populating the fillable section of the template, receiving a test template for the rule, the test template including an additional fillable section; and

populating the additional fillable section based on the rule.

13. The method of claim 12 , further comprising:

storing the rule and the test for the rule in a repository.

14. The method of claim 8 , wherein the difference comprises semantic information about the source version of the dependency and the target version of the dependency.

15. A non-transitory computer-readable medium comprising program code that is executable by a processor for causing the processor to:

receive a source version of a dependency of a software application and a target version of the dependency of the software application, the dependency being used by the software application to perform one or more tasks of the software application;

compare the source version of the dependency to the target version of the dependency to determine a difference between the source version of the dependency and the target version of the dependency;

receive a template for a rule indicating a location in the source version of the dependency to be modified for the software application to support the target version of the dependency, the template including a fillable section;

populate the fillable section of the template with a value based on the difference between the source version of the dependency and the target version of the dependency; and

output a report including the rule and a modification for the source version of the dependency for the software application to support the target version of the dependency.

16. The non-transitory computer-readable medium of claim 15 , further comprising program code that is executable by a processor for causing the processor to:

determine a plurality of differences between the source version of the dependency and the target version of the dependency;

classify each difference of the plurality of differences based on a severity of the difference;

filter the plurality of differences into a subset of differences, the severity of each difference in the subset of differences being above a threshold; and

generate, for each difference of the subset of differences, the rule by populating the fillable section of the template based on the difference.

17. The non-transitory computer-readable medium of claim 15 , further comprising program code that is executable by a processor for causing the processor to select the template from a plurality of templates based on the difference between the source version of the dependency and the target version of the dependency.
