问题 I want to build Eclipse JDT Core from source code via Git. Naïvely, I cloned git://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.git and tried to run mvn validate (the most basic of Maven phases) from the Git master branch but this failed with errors below. I am a Debian Linux user with Maven 3.0.5 and JDK 1.7 installed. I am interested to hack on class ASTParser, which can parse Java code. I realise building Eclipse projects is hard, but I cannot find the definitive "recipe" page anywhere on

问题 After install of 2019-12 version of Eclipse I can't set black background while using Dark theme and Default set of colors. If I change color in General -> Editors -> Text Editors -> Appearance color options -> Background color - I see line numbers background color get changed to my choice, while text area remain in same dark grey, regardless of the color I choose. I tried to manually edit epf preferences and import them back, but even this way doesn't work. Is there a some change/bug in

问题 Does anyone have an example how to redefine an import in a java source file using the Eclipse JDT Core API? I have the following (which does not work) and it's driving me mad. try { for (IPackageFragmentRoot root : project.getPackageFragmentRoots()) { if (root.getElementName().equals("src")) { for (ICompilationUnit unit : root.getPackageFragment("soap.service.implementation.strongProfile.delegate").getCompilationUnits()) { System.out.println(unit.getElementName()); for (IImportDeclaration dec

问题 Sometimes, I get this message in the status bar when I press F3 on a Type in a Java editor: Current text selection cannot be opened in an editor When I copy the selection into the clipboard and use Ctrl+Shift+T to open the "Open Type" dialog, I can paste the value and it will display the type and I can open it. The type is on the class path (no compile errors). In other Java editors in the same project, F3 / Ctrl-Click works. In the "broken" editor, it only works on internal fields and

问题 I encounter a very strange problem with Maven and Eclipse compiler. While in Eclipse+m2eclipse, I have no problem compiling a small project (archetype quick start) with the following single class. package test.test; import com.Ostermiller.util.CSVParser; public class TestCaseSensitive { CSVParser csvParser; } Ostermiller utils is added to pom.xml. Eclipse Kepler compiles the project. Next, mvn compile works out-of-the-box. Now the issue, I switch to compiler 3.1 and asks for Eclipse compiler

问题 When I visit a MethodInvocation node during AST traversal, I want to know if it lies in the IfStatement then part or else part or in the expression part. The then part can be a complete block of code but I think my code is handling only a single then statement. Here is the code snippet for visiting a method invocation @Override public boolean visit(MethodInvocation node) { StructuralPropertyDescriptor location = node.getLocationInParent(); setNodeRegion(location); Here is how I want to set

问题 I have written one eclipse osgi plugin that runs cleanup and formatting actions on java files present in eclipse project. Some thing like: Run batch file that has eclipse command It open's eclipse editor Loads eclipse project passed as parameter in batch command Run cleanup and formatting actions Closes eclipse Now my problem is I need to track the files that has been changed by this action. I am performing cleanup changes using cleanUpsAction that runs as thread over multiple files and forks

问题 I'm using the org.eclipse.jdt parser. I want to rewrite this code: public void foo(){ ... ... if(a>b) ... ... } into this: public void foo(){ ... ... System.out.println("hello"); if(a>b) ... ... } Supposing that ifnode is an IF_STATEMENT node, I can do something similar to this: Block block = ast.newBlock(); TextElement siso = ast.newTextElement(); siso.setText("System.out.println(\"hello\");"); ListRewrite listRewrite = rewriter.getListRewrite(block, Block.STATEMENTS_PROPERTY); listRewrite
