NAME

java_remove_imports - remove import statements from Java source files

SYNOPSIS

%java_remove_imports [optional flags] <matcher>... [file path]...

DESCRIPTION

This macro removes import statements from Java source files. The script matches all non-whitespace content following the 'import [static]' statement against all patterns provided via the -p flag and all simple class names against names provided by the -n flag.

File path arguments are handled the following way:

•Symlinks are ignored.

•Regular files are handled regardless of the file name.

•Directories are traversed recursively and all .java files are handled.

Arguments can be specified in arbitrary order.

Matcher is one of:

-n <name>

Simple class name to be matched against the simple names of imported symbols. Names are matched for exact equality. Can be specified multiple times.

-p <pattern>

Regex patterns to be matched against imported symbols. Each imported symbol found in the code is matched against each pattern. Can be specified multiple times.

Optional flags:

-s, --strict

Fail if any of the user provided arguments were redundant.

EXAMPLES

Example of usage in a .spec file:

%java_remove_imports src -n Nullable

Examples of patterns:

•Import statements present in Java source file:

1) import java.lang.Runnable;
2) import java.util.List;
3) import static java.util.*;
4) import static java.lang.String.valueOf;
5) import com.google.common.util.concurrent.Service;
