Release Notes

google/error-prone (com.google.errorprone:error_prone_core)

v2.42.0: Error Prone 2.42.0

New checks:

• ExplicitArrayForVarargs: discourage unnecessary explicit construction of an array to provide varargs.
• FloggerPerWithoutRateLimit: discourage Flogger's perUnique without rate limiting
• StringJoin: Ban String.join(CharSequence) and String.join(CharSequence, CharSequence)
• ThreadBuilderNameWithPlaceholder: Do not allow placeholders in Thread.Builder.name(String) or name(String, int).

Changes:

• The return type of ASTHelpers.asFlagSet has changed. The previous type was EnumSet<Flags.Flag>, where Flags.Flag is an enum in the javac class Flags. A recent JDK change has replaced that enum with a new top-level enum called FlagsEnum. It is not possible to change ASTHelpers.asFlagSet in a way that would be type-safe and compatible with the enums from JDKs both before and after the change. Instead, the method now returns ImmutableSet<String>, where the strings come from the toString() of the enum constants. That means they are "native", "abstract", etc.
• Flag IO.print[ln]() in SystemOut.

v2.39.0: Error Prone 2.39.0

Changes:

• Temporarily downgrade to Guava 33.4.0 (#​5108)

Checks:

• BooleanLiteral: Prefer true to Boolean.TRUE
• ExpensiveLenientFormatString: Renamed from PreconditionsExpensiveString, detects unnecessary calls to String.format in the arguments of lenient formatting methods.

Issues: #​4996, #​5045

Full changelog: google/error-prone@v2.38.0...v2.39.0

v2.38.0: Error Prone 2.38.0

New checks:

• AddNullMarkedToPackageInfo: adds @org.jspecify.annotations.NullMarked annotation to package-info files
• IntLiteralCast: Suggests a literal of the desired type instead of casting an int literal to a long, float, or double
• MisleadingEmptyVarargs: Discourages calling varargs methods that expect at least one argument with no arguments, like Mockito's thenThrow
• PreconditionsExpensiveString: Discourages expensive string formatting in Guava Preconditions checks
• SelfSet: Detects mistakes like proto.setFoo(proto.getFoo())
• UnnecessaryCopy: detect unnecessary copies of proto Lists and Maps.

Closed issues: #​4924, #​4897, #​4995

Full changelog: google/error-prone@v2.37.0...v2.38.0

v2.37.0: Error Prone 2.37.0

Changes:

• The annotations that were previously in error_prone_type_annotations have been been merged into error_prone_annotations. error_prone_type_annotations is now deprecated, and will be removed in a future release.

New checks:

• AssignmentExpression - The use of an assignment expression can be surprising and hard to read; consider factoring out the assignment to a separate statement.
• IntFloatConversion - Detect calls to scalb that should be using the double overload instead
• InvalidSnippet - Detects snippets which omit the : required for inline code.
• JUnit4EmptyMethods - Detects empty JUnit4 @Before, @After, @BeforeClass, and @AfterClass methods.
• MockIllegalThrows - Detects cases where Mockito is configured to throw checked exception types which are impossible.
• NegativeBoolean - Prefer positive boolean names.
• RuleNotRun - Detects TestRules not annotated with @Rule, that won't be run.
• StringConcatToTextBlock - Replaces concatenated multiline strings with text blocks.
• TimeInStaticInitializer - Detects accesses of the system time in static contexts.

Closed issues:

• Propagate check flags in patch mode (#​4699)
• Fixes a crash in ComputeIfAbsentAmbiguousReference (#​4736)
• Show the field name in HidingField diagnostics (#​4775)
• Add support for jakarta annotations to some checks (#​4782)
• FloatingPointAssertionWithinEpsilonTest depends on default locale (#​4815)
• @InlineMe patching of Strings.repeat produces broken code (#​4819)
• Fix a crash in IdentifierName on unnamed (_) variables (#​4847)
• Fix a crash in ArgumentParameterSwap (#​490)
