Has minimum Java version

Recipe IDorg.openrewrite.java.search.HasMinimumJavaVersionArtifactorg.openrewrite:rewrite-java

Finds source files when the oldest Java version in use meets the supplied minimum version. Java version is attributed per source set (for example src/main/java and src/test/java), so the oldest Java version in use is the lowest version across every source set of every subproject in a repository. For example, the main source set of a project may use Java 8 while its test source set uses Java 17; in that case the oldest Java version in use is Java 8.

mod config recipes jar install org.openrewrite:rewrite-java:RELEASE

Options

NameTypeDescription
versionrequiredStringA minimum version number or a node-style semver selector. Plain values like 17 or 17.0.1 match that version or higher. To match an exact version, use HasJavaVersion instead.
e.g. 17
checkTargetCompatibilityBooleanThe source and target compatibility versions can be different. This option allows you to check against the target compatibility version instead of the source compatibility version.
e.g. 17.X
