Usage

You’ll need the Moderne CLI configured before running the command below.

mod run . --recipe org.openrewrite.java.ChangeMethodInvocationReturnType --recipe-option "methodPattern=org.mockito.Matchers anyVararg()" --recipe-option "newReturnType=long"

If the recipe isn’t available locally, install it with:

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

Options

Name	Type	Description
`methodPattern`required	`String`	A method pattern is used to find matching method invocations. For example, to find all method invocations in the Guava library, use the pattern: `com.google.common..#(..)`. The pattern format is `<PACKAGE>#<METHOD_NAME>(<ARGS>)`. `..` includes all subpackages of `com.google.common`. `(..)` matches any method name with any number of arguments. For more specific queries, like Guava's `ImmutableMap`, use `com.google.common.collect.ImmutableMap#*(..)` to narrow down the results. e.g. `org.mockito.Matchers anyVararg()`
`newReturnType`required	`String`	The fully qualified new return type of method invocation. Parameterized types like `java.util.Set<java.lang.String>` are supported; `java.lang` type arguments may use their simple name, e.g. `java.util.List<String>`. Nested types may be written with a `$` separator, e.g. `mockwebserver3.MockResponse$Builder`; dots also work, e.g. `mockwebserver3.MockResponse.Builder`, in which case the first segment that is followed only by segments starting with an uppercase letter is taken to be the outermost type. e.g. `long`
