问题 I am trying to configure latest Eclipse for C++ (Oxygen) to work with gtkmm. How can I remove errors from Eclipse such as unresolved symbols and gtkmm header files. I am able to compile from command line using g++ and pkg-config flags. How can I do same thing from the Eclipse IDE? I am using latest IDE 2019 version. 回答1: I have been using gtkmm and Eclipse for a while now. Here is how I set it up to get both working properly together. To illustrate this, I will take the basic example from the

问题 I am trying to run a Spark maven Scala Project in eclipse . when i run the scala class , i get this error : Exception in thread "main" java.lang.NumberFormatException: Not a version: 9 at scala.util.PropertiesTrait$class.parts$1(Properties.scala:184) at scala.util.PropertiesTrait$class.isJavaAtLeast(Properties.scala:187) at scala.util.Properties$.isJavaAtLeast(Properties.scala:17) .... what is wrong ? what is a version 9 ? 回答1: Scala does not work with Java 9 out of the box just yet - there

问题 It seems, that in my Eclipse Oxygen 3 transitive dependencies are not resolved in Plugin-Projects. Consider the following Project with A depending solely on B, and B depending on C: While running A in JDK 1.8 turns out fine (as expected), in JDK 9 I get the well known Exception in thread "main" java.lang.NoClassDefFoundError: c/C at b.B.<init>(B.java:9) at a.A.main(A.java:8) Caused by: java.lang.ClassNotFoundException: c.C at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass

问题 My application isn't running correctly with Java 9. In order to debug it, I upgraded to Eclipse 4.7 (oxygen) since Neon doesn't have Java 9 support, and applied the Java 9 support patch. After doing so, eclipse was failing to load any of my pre-existing Java Applications. Thinking it might be a version difference thing, I deleted them, to try re-adding. But when I click the "New" button to add a configuration, nothing happens. If I double-click "Java Application," I get the following error:

问题 I desperately try to get Eclipse Oxygen to run Java 9 on Mac OSX, but I somehow seem to fail. Steps I have done so far: Installed the Java 9 JDK in /Library/Java/JavaVirtualMachines/jdk-9.jdk (next to the already installed /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk) Installed the "Java 9 Support (BETA) for Oxygen 4.7" plugin from the Eclipse market place (I have Oxygen 4.7 for Java EE Developers installed) Added the line "--add-modules=java.se.ee" after the -vmargs line in eclipse.ini

问题 I'm doing some tests with the last Eclipse developer builds, the Oxygen RC3 . I know it's only a RC product, but in the milestones there was no problem with the Axis2 runtime. Here and now the Axis Runtime it's not present. When I try to run the wizard and create the Web Service, I just don't see the option to set Axis2 runtime, just the Axis runtime. Also I tried to install the plugins moving them into the dropins folder, running Eclipse with the -console option from the command line

问题 Why do projects disappear from the project explorer in Oxygen? I can see them briefly after starting Eclipse but then they disappear. They can't be re-added or imported because it says they already exist. I re-cloned the project from git into a different directory, deleted .classpath, .settings and .project and tried to import as a file system but can't advance. The next button is greyed out. Import projects from folder or archive allowed me to import my clone but then it dissappears again. I

问题 I want to use java9 on my gradle project inside eclipse oxygen. When I run: Run as> Gradle Test on GreeterTest.java with the following code: package hello.test; import static org.junit.jupiter.api.Assertions.*; import org.junit.jupiter.api.Test; import hello.Greeter; class GreeterTest { @Test void test() { Greeter greeter = new Greeter(); assertEquals("Hello world", greeter.sayHello()); } } and with the class I test as: package hello; public class Greeter { public String sayHello() { return

问题 I get an annoying welcome screen whenever I start eclipse. How can I get it to skip the welcome and go straight to the workbench when I start it? 回答1: For Eclipse Neon: Open Eclipse Uncheck the box in the bottom right hand corner (Show every time) Close the welcome screen Edit: Still correct for Eclipse Oxygen, Photon and 2018-12 回答2: The welcome screen is displayed whenever you first open eclipse with a new workspace. Once you close the welcome screen, this is noted in the workspace, and on

问题 The maven project example that is given below shows an error in module-info.java in Eclipse Oxygen: log4j.api cannot be resolved to a module. If I remove the line <packaging>pom<packaging> from pom.xml the error disappears. However, I need to use pom packaging. If I use Java8 without module definitions, the maven part in my real world example works very well. Trying to migrate to Java9 confronted me with this new issue. First I thought I would not correctly reference the log4j dependency.
