An example project on how we use the nebula plugins on a simple project

2. Resolution rules

a. Substitution rules

Dependency a depends on substitute:1.0.0. A substitution rule updates to substitute:1.0.1

./gradlew dependencyInsight --dependency substitute --configuration testCompile

> Task :dependencyInsight
sustitutionrule:substitute:1.0.1 (substitution because version 1.0.0 was accidentally released from dev_branch)

sustitutionrule:substitute:1.0.0 -> 1.0.1
\--- sustitutionrule:a:1.0.0
     \--- testCompile

Direct dependency on directsubstitute:2.0.0. A substitution rule updates directsubstitute:2.1.0

./gradlew dependencyInsight --dependency directsubstitute --configuration compile

> Task :dependencyInsight
sustitutionrule:directsubstitute:2.1.0 (substitution because version 2.0.0 was accidentally released from dev_branch)

sustitutionrule:directsubstitute:2.0.0 -> 2.1.0
\--- compile

Dependency arange0 depends on rangesubstitute:2.0.0, arange1 depends on rangesubstitute:2.2.0, A rule updates range rangesubstitute:[2.0.0,2.5.0] to 2.5.1.

./gradlew dependencyInsight --dependency rangesubstitute --configuration compile

> Task :dependencyInsight
sustitutionrule:rangesubstitute:2.5.1 (substitution because range contains a bug)

sustitutionrule:rangesubstitute:2.0.0 -> 2.5.1
\--- sustitutionrule:arange0:1.0.0
     \--- compile

sustitutionrule:rangesubstitute:2.2.0 -> 2.5.1
\--- sustitutionrule:arange1:1.0.0
     \--- compile

Dependency asub depends on sub-all:1.0.0, A rule update it to sub-core:1.0.0.

./gradlew dependencyInsight --dependency sub-all --configuration compileOnly

> Task :dependencyInsight
sustitutionrule:sub-core:1.0.0 (substitution because sub-all is pure evil)

sustitutionrule:sub-all:1.0.0 -> sustitutionrule:sub-core:1.0.0
\--- sustitutionrule:asub:1.0.0
     \--- compileOnly

b. Alignment rule

Dependency b0 depends on align0:1.0.1, b1 depends on align1:1.1.0. Alignment rule should upgrade all align* to 1.1.0

./gradlew dependencyInsight --dependency align --configuration compileClasspath

> Task :dependencyInsight
alignmentrule:align0:1.1.0 (aligned to 1.1.0 by align-alignfamily)

alignmentrule:align0:1.0.1 -> 1.1.0
\--- alignmentrule:b0:1.0.0
     \--- compileClasspath

alignmentrule:align1:1.1.0
\--- alignmentrule:b1:1.0.0
     \--- compileClasspath

A project directly depends on direct-align0 and direct-align1. Both should upgrade to 1.1.0

./gradlew dependencyInsight --dependency align --configuration compileClasspath

alignmentrule:direct-align0:1.1.0 (aligned to 1.1.0 by align-directalign)

alignmentrule:direct-align0:1.0.1 -> 1.1.0
\--- compileClasspath

alignmentrule:direct-align1:1.1.0
\--- compileClasspath

Dependency b0 depends on align0:1.0.1, b1 depends on align1:1.1.0, b2 depends on align2:1.0.2. The dependency align2 is exluded from alignment. align0 and align1 should have the same version 1.1.0

./gradlew dependencyInsight --dependency align --configuration compileClasspath

alignmentrule:exclude-align0:1.1.0 (aligned to 1.1.0 by align-excludealigns)

alignmentrule:exclude-align0:1.0.1 -> 1.1.0
\--- alignmentrule:exclude-b0:1.0.0
     \--- compileClasspath

alignmentrule:exclude-align1:1.1.0
\--- alignmentrule:exclude-b1:1.0.0
     \--- compileClasspath

alignmentrule:exclude-align2:1.0.2
\--- alignmentrule:exclude-b2:1.0.0
     \--- compileClasspath

Dependency bforce0 depends on alignforce0:1.0.1, bforce1 depends on alignforce1:1.0.2. We force alignforce0 to 2.0.0, Both should be aligned to 2.0.0.

./gradlew dependencyInsight --dependency align --configuration compileClasspath

alignmentrule:alignforce0:2.0.0 (forced)

alignmentrule:alignforce0:1.0.1 -> 2.0.0
\--- alignmentrule:bforce0:1.0.0
     \--- compileClasspath

alignmentrule:alignforce1:2.0.0 (aligned to 2.0.0 by align-alignforce)

alignmentrule:alignforce1:1.0.2 -> 2.0.0
\--- alignmentrule:bforce1:1.0.0
     \--- compileClasspath

c. Reject rule

Depend on reject:1.+, We have reject rule on 1.0.1. It should pick only existing 1.0.0

./gradlew dependencyInsight --dependency reject --configuration runtime

> Task :dependencyInsight
rejectrule:reject:1.0.0

rejectrule:reject:1.+ -> 1.0.0
\--- runtime

d. Replacement rule

Direct dependency replacementex0 depends on replacee:1.0.0, another direct dependency replacementex1 depends on replacement:2.0.0. replacee should be replaced by replacement.

./gradlew dependencyInsight --dependency replacee --configuration runtime

> Task :dependencyInsight
replacerule:replacement:2.0.0 (replacement replacerule:replacee -> replacerule:replacement)

replacerule:replacee:1.0.0 -> replacerule:replacement:2.0.0
\--- replacerule:replacementex0:1.0.0
     \--- runtime

3. Recommender project that uses OverrideTransitives mode

"Closer" defined dependencies in recommender override transitive dependencies versions. See override_project_example

./gradlew dependencyInsight --dependency transitivedeb --configuration compile

> Task :dependencyInsight
overridestrategy:transitivedeb:1.0.0 (recommend 1.0.0 via override transitive recommendation)

overridestrategy:transitivedeb:1.0.1 -> 1.0.0
\--- overridestrategy:a:1.0.0
     \--- compile
