+# Eclipse JDT over Javac
+
+This fragment contains a Javac backend (instead of ECJ) for JDT features:
+* error reporting/reconciling
+* build/compilation
+* indexing
+* code selection (Ctrl + click / hover)
+* code completion (requires JDT fork bundle + opt-out flag)
+* search/match (requires JDT fork bundle + opt-out flag)
+
+## ❓ Why?
+
+Some background...
+* These days, with more frequent and more features Java releases, it's becoming hard for JDT to **cope with new Java features on time** and **facilitate support for upcoming/preview features before Java is released so JDT can participate to consolidation of the spec**. Over recent releases, JDT has failed at providing the features on time. This is mostly because of the difficulty of maintaining the Eclipse compiler: compilers are difficult bits of code to maintain and it takes a lot of time to implement things well in them. There is no clear sign the situation can improve here.
+* The Eclipse compiler has always suffered from occasional **inconsistencies with Javac** which end-users fail at understanding. Sometimes, ECJ is right, sometimes Javac is; but for end-users and for the ecosystem, Javac is the reference implementation and it's behavior is what they perceive as the actual specification
+* JDT has a very strong ecosystem (JDT-LS, plugins) a tons of nice features, so it seems profitable to **keep relying higher-level JDT APIs, such as model or DOM** to remain compatible with the ecosystem
+
+🎯 The technical proposal here mostly to **allow Javac to be used at the lowest-level of JDT**, under the hood, to populate higher-level models that are used in many operations; named the JDT DOM and IJavaElement models. It is expected that if we can create a good DOM and IJavaElement structure with another strategy (eg using Javac API), then all higher level operations will remain working as well without modification.
+
+## 📥 Install on top of existing JDT in your Eclipse IDE
+
+Assuming you have Eclipse IDE well configured, just click the following link 👇 https://mickaelistria.github.io/redirctToEclipseIDECloneCommand/redirectToMarketplace.html?entryId=6444683
+
+**OR**
+
+Using the _Help > Install New Software_ dialog and pointing to https://ci.eclipse.org/ls/job/jdt-core-incubator/job/dom-with-javac/lastSuccessfulBuild/artifact/repository/target/repository/ p2 repository,
+install the _Javac backend for JDT_ artifact. Installing it will also tweak your `eclipse.ini` file to add the relevant options.
+
+Note that some required feature switches are not yet available in upstream JDT (see above) and thus will still default to ECJ.
+
+## ⌨️ Development
+
+### ⌨️ Contribute
+
+From a PDE-able IDE using a target platform that is suitable for JDT development (usually default case).
+
+You'll need to import the code of `org.eclipse.jdt.core` and `org.eclipse.jdt.core.javac` from this branch in your Eclipse workspace; and create a Launch Configuration of type "Eclipse Application" which does include the `org.eclipse.jdt.core` bundle. Go to _Arguments_ tab of this launch configuration, and add the following content to the _VM arguments_ list:
+
+```
+-DCompilationUnit.DOM_BASED_OPERATIONS=true -DICompletionProvider=org.eclipse.jdt.core.dom.DOMCompletionProvider -DSourceIndexer.DOM_BASED_INDEXER=true -DICompilationUnitResolver=org.eclipse.jdt.core.dom.JavacCompilationUnitResolver -DAbstractImageBuilder.compilerFactory=org.eclipse.jdt.internal.javac.JavacCompilerFactory --add-opens jdk.compiler/com.sun.tools.javac.main=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.platform=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.platform=ALL-UNNAMED --add-opens jdk.compiler/com.sun.tools.javac.resources=ALL-UNNAMED --add-opens jdk.zipfs/jdk.nio.zipfs=ALL-UNNAMED --add-opens java.compiler/javax.tools=ALL-UNNAMED --add-opens java.base/sun.nio.ch=ALL-UNNAMED
+```
+
+Those arguments are automatically added to your eclipse.ini file when installing with p2.
+
+* `CompilationUnit.DOM_BASED_OPERATIONS=true`/`CompilationUnit.codeComplete.DOM_BASED_OPERATIONS` / `SourceIndexer.DOM_BASED_INDEXER=true` system properties enables some operations to use build and DOM instead of ECJ Parser (so if DOM comes from Javac, ECJ parser is not involved at all)
+* `--add-opens ...` as visible in the `org.eclipse.jdt.core.javac/META-INF/p2.inf` file to allow to access internal API of the JVM, including Javac ones
+* `ICompilationUnitResolver=org.eclipse.jdt.core.dom.JavacCompilationUnitResolver` system property enables using Javac instead of ECJ to create JDT DOM AST.
+* `AbstractImageBuilder.compilerFactory=org.eclipse.jdt.internal.javac.JavacCompilerFactory` system property instruct the builder to use Javac instead of ECJ to generate the .class file during build.
+
+Those properties can be set separately, which can useful when developing one particular aspect of this proposal, which property to set depends on what you want to focus on.
+
+### 📈 Progress
+
+* Refactorings in upstream JDT got merged in order to allow alternative (non-ECJ strategies) for
+ * reconciling model/errors using DOM ✔DONE
+ * generating DOM from alternative parser ✔DONE
+ * codeSelect ✔DONE
+ * indexing ✔DONE
+ * completion ⌨️IN PROGRESS
+ * search/match ⌨️IN PROGRESS
+ * compiler ✔DONE
+* Javac backend for
+ * producing Javac AST & Symbols ✔DONE (incl. annotation processing)
+ * Javac->JDT AST conversion ✔DONE (incl. annotation processing)
+ * binding conversion ✔DONE
+ * JavacCompiler ✔DONE
+
+
+🤔 What are the potential concerns:
+* **Memory cost** of retaining Javac contexts needs to be evaluated (can we get rid of the context earlier? Can we share subparts of the concerns across multiple files in the project?...)
+* It seems hard to find reusable parts from the **CompletionEngine**, although many proposals shouldn't really depend on the parser (so should be reusable)
+
+
+😧 What are the confirmed concerns:
+* **Null analysis** and some other **static analysis** are coded deep in ECJ and cannot be used with Javac. A solution can be to leverage another analysis engine (eg SpotBugs, SonarQube) deal with those features.
+* At the moment, Javac cannot be configured to **generate .class despite CompilationError** in them like ECJ can do to allow updating the target application even when some code is not complete yet
+ * We may actually be capable of hacking something like this in Eclipse/Javac integration (although it would be best to provide this directly in Javac), but running a 1st attempt of compilation, collecting errors, and then alterating the working copy of the source passed to Javac in case of error. More or less `if (diagnostics.anyMatch(getKind() == "error") { removeBrokenAST(diagnostic); injectAST("throw new CompilationError(diagnostic.getMessage()")`.
