From 9148294f78a8e646ee131ca182a9b692bc028fdb Mon Sep 17 00:00:00 2001 From: Reinier Zwitserloot Date: Sat, 29 Aug 2020 04:14:10 +0200 Subject: [testing] [eclipse] [#2413] Eclipse tests now more expansive We now test generating a level2-DOM from our level1-AST (eclipse has 3 levels of ASTs, more or less), only if that is possible, i.e. only if the full eclipse is available. This requires using a test target named `eclipse-X`, and not one of the `ecjX` ones. This is the change that requires the massive update to the build system. About 6 tests, including a newly added one about @Delegate, now fail. These failures would usually not cause instant failure in eclipse, but can cause errors during save actions and will likely mess with other things in weird ways, such as messing up syntax highlighting. Yes, this commit now makes a bunch of cases fail the unit tests, but that is representative of actual errors in lombok, so I'm checking it in as is (without this commit, the problem is still there, the tests are just incapable of detecting it). --- test/core/src/lombok/RunTestsViaEcj.java | 79 ++++++++++++++++++++++++++++++-- 1 file changed, 76 insertions(+), 3 deletions(-) (limited to 'test/core/src/lombok/RunTestsViaEcj.java') diff --git a/test/core/src/lombok/RunTestsViaEcj.java b/test/core/src/lombok/RunTestsViaEcj.java index ab28cb0c..739d6316 100644 --- a/test/core/src/lombok/RunTestsViaEcj.java +++ b/test/core/src/lombok/RunTestsViaEcj.java @@ -1,5 +1,5 @@ /* - * Copyright (C) 2010-2014 The Project Lombok Authors. + * Copyright (C) 2010-2020 The Project Lombok Authors. * * Permission is hereby granted, free of charge, to any person obtaining a copy * of this software and associated documentation files (the "Software"), to deal @@ -23,25 +23,33 @@ package lombok; import java.io.File; import java.io.StringWriter; +import java.nio.file.Files; +import java.nio.file.Path; +import java.nio.file.Paths; import java.util.ArrayList; import java.util.Collection; +import java.util.Enumeration; import java.util.HashMap; import java.util.Iterator; import java.util.List; import java.util.Locale; import java.util.Map; import java.util.concurrent.atomic.AtomicReference; +import java.util.jar.JarEntry; +import java.util.jar.JarFile; import lombok.eclipse.Eclipse; import lombok.javac.CapturingDiagnosticListener.CompilerMessage; +import org.eclipse.jdt.core.JavaCore; import org.eclipse.jdt.core.compiler.CategorizedProblem; +import org.eclipse.jdt.core.dom.AST; +import org.eclipse.jdt.core.dom.CompilationUnit; import org.eclipse.jdt.internal.compiler.CompilationResult; import org.eclipse.jdt.internal.compiler.Compiler; import org.eclipse.jdt.internal.compiler.ICompilerRequestor; import org.eclipse.jdt.internal.compiler.IErrorHandlingPolicy; import org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration; -import org.eclipse.jdt.internal.compiler.batch.CompilationUnit; import org.eclipse.jdt.internal.compiler.batch.FileSystem; import org.eclipse.jdt.internal.compiler.env.ICompilationUnit; import org.eclipse.jdt.internal.compiler.impl.CompilerOptions; @@ -103,7 +111,8 @@ public class RunTestsViaEcj extends AbstractRunTests { }; String source = readFile(file); - final CompilationUnit sourceUnit = new CompilationUnit(source.toCharArray(), file.getName(), encoding == null ?
