Version 4.5.1 is the last one available from central - http://mvnrepository.com/artifact/org.eclipse.jdt.core.compiler/ecj/4.5.1
Unfortunately there is a nasty bug, which was fixed only in 4.5.2.
I cannot seem to find a binary package anywhere. I tried building it from sources but failed (details below). What is the recommended way to obtain 4.5.2 binary?
I tried https://github.com/eclipse/eclipse.jdt.core but it doesn't have any relevant tags.
I tried building the tag R4_5_2 from https://git.eclipse.org/c/jdt/eclipse.jdt.core.git/tag/?h=R4_5_2
Suprisingly it still has a snapshot version 4.5.2-SNAPSHOT and requires a parent of the same version. I can try building the parent project, but I'd expect it to be already available in some repository etc. Before proceeding I'd like at least to know if this path is going to lead anywhere.
Finally I came across Project Tycho but I think this is only relevant if I'm creating a new plugin.
I've found one here by random googling: http://download.eclipse.org/eclipse/downloads/drops4/R-4.5.2-201602121500/#JDTCORE
However the timestamp is different than what I get in my Eclipse Mars. Here it's 20160212-1500 and in Eclipse I have 20160128-0629
I am trying to get started with Eclipse SCADA and import the projects from their git repository.
I have cloned the following projects:
org.eclipse.scada.external
org.eclipse.scada.utils
org.eclipse.scada.base
org.eclipse.scada.protocols
org.eclipse.scada.core
org.eclipse.scada.releng
For each project I did mvn verify in the parent folder and imported the projects in Eclipse. I also changed target platform. However, I still seem to have problems with their dependencies.
Any help would really be appreciated.
Actually the Eclipse SCADA java projects are not developed with "Maven first". So you should disregard maven completely while in the IDE. The maven build is basically only used to build the project unattended.
The issue with the target platform is more complex. We were a bit sloppy in providing a always working target platform (and it is actually difficult to keep them up to date, since the versions of the bundles are fix).
I made a target platform file for the current version, you can find it here: https://gist.github.com/CptMauli/ec6eda37734f0108510f
To make it work properly please download a classic eclipse put it somewhere and create an environment variable ECLIPSE_432_HOME which points to it. Alternatively you can just change the first entry in the target file and point it directly to it.
The reason behind it is, if you would use your own eclipse installation, it is possible that bundles installed there conflict with bundles provided in the target platform or from your workspace. This is actually mostly not even a problem when compiling, but as soon as you start a client or a server, Eclipse will complain about duplicated bundles.
If you have any more questions please go to our mailing list: https://dev.eclipse.org/mailman/listinfo/scada-dev
or our google group: https://groups.google.com/forum/#!forum/openscada

Does anyone know how to properly setup an Eclipse project in order to build the Androlate plugin; which can be found at http://code.google.com/p/androlate/issues/list?
I need this in order to replace the older Google translation code - which no longer works - with the newer Bing Translation code (see Issue #2 of this plugin for more information).
I've never built an Eclipse plugin before and all my attempts so far for this plugin have failed. However, I'm able to build the plugin examples given by Eclipse and I've also be able to build the complex Motodev plugin (http://www.motorola.com/sites/motodev/library/motodev_core_plugins.html); therefore my environment (Eclipse Juno) should be correct.
First, the source for this plugin is lacking its .project File; so I had to trick Eclipse in order to import this project into the workspace by overwriting a new plugin project over the source files. (BTW, does anyone knows why is it so difficult to simply add an existing project to the current workspace in Eclipse? Why did they have to make such a simple task so difficult?).
Second, when I try to launch this plugin under Debug Mode as an Eclipse application, I first got multiple error messages: Can't find bundle for base name feature, locale en_US.
Finally, when I try the plugin itself, I got the error Logging bundle must not be null at the line 60 of the AndrolateWizard.java file; indicating that the call to Platform.getBundle(Activator.PLUGIN_ID) at the previous line (line 59) return a null bundle.
This is because the Plugin Id specified in the activator does not match the plugin id specified in your MANIFEST.MF [Check and correct it to com.cicadalane.androlate]
Old post, but here is an androlate gradle plugin if it helps anyone https://github.com/ayvazj/gradle-androlate-plugin
I recently gave up trying to use Scala in Eclipse (basic stuff like completion doesn't work). So now I'm trying IntelliJ. I'm not getting very far.
I've been able to edit programs (within syntax highlighting and completion... yay!). But I'm unable to run even the simplest "Hello World". This was the original error:
Scala signature Predef has wrong version
Expected 5.0
found: 4.1 in .... scala-library.jar
But that was yesterday with IDEA 9.0.1. See below...
UPDATE
Today I uninstalled IntelliJ 9.0.1, and installed 9.0.2 Early Availability, with the 4/14 stable version of the Scala plug-in.
Then I setup a project from scratch through the wizards:
new project from scratch
JDK is 1.6.u20
accept the default (project) instead of global / module
accept the download of Scala 2.8.0beta1 into project's lib folder
Created a new class:
object hello {
def main(args: Array[String]) {
println("hello: " + args);
}
}
For my efforts, I now have a brand-new error :)
Here it is:
Scalac internal error: class java.lang.ClassNotFoundException [java.net.URLClassLoader$1.run(URLClassLoader.java:202), java.security.AccessController.doPrivileged(Native Method), java.net.URLClassLoader.findClass(URLClassLoader.java:190), java.lang.ClassLoader.loadClass(ClassLoader.java:307), sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301), java.lang.ClassLoader.loadClass(ClassLoader.java:248), java.lang.Class.forName0(Native Method), java.lang.Class.forName(Class.java:169), org.jetbrains.plugins.scala.compiler.rt.ScalacRunner.main(ScalacRunner.java:72)]
FINAL UPDATE
I uninstalled 9.0.2 EA and reinstalled 9.0.1, but this time went with the 2.7.3 version of Scala rather than the default 2.7.6, because 2.7.3 is the one shown in the screen-shots at the IntelliJ website (I guess the screen-shots prove that they actually tested this version!). Now everything works!!!
I have encountered the same scalac error when trying to run a Scala project in Intellij Idea 9.0.2 and I've managed to find a solution by chance :). These are the steps I took in creating the project and running it.
I have created a Scala project in Intellij Idea 9.0.2 final (it was released today). I have installed the Scala plugin, restarted the IDE and created a new Scala project (with the name "TestScala") with scala-2.8.0.Beta1 as project library. Once the project is created and the scala libraries downloaded, I have created a Test.scala file with the following content:
object Test {
def main(args:Array[String]){
println("hello")
}
}
After that, I created a launch configuration ("Edit Configurations"), choosing the "Application" template. I set as main class Test and choose the project name ("TestScala") in the "Use classpath and JDK of module" combo box. When I run the configuration I get the same error as you reported ("Scalac internal error: class java.lang.ClassNotFoundException") .
Now comes the freaky part :). I right click on the project, choose "Module Settings", have a look on all settings but I don't change anything . Click "apply" and "ok", try to run configuration again and it works :) .
I use Intellij Idea 9.0.2 the final release (build 95-66); Ubuntu 9.10 and JDK 1.6.0_18. I also have to mention that I had a JDK configured in Intellij, otherwise there is an extra step to configure it.
UPDATE:
When checking the setting of the module, one needs to click on the Module->Scala and Facets->Scala (expand it and click on Scala(ProjectName)) . Both of these settings are about the scala compiler and scala library location. I would guess these values are not properly set when the project is created but are saved once the user touches them and saves the settings.
To answer your question, it's difficult to get a working IDE for Scala for two reasons:
(a) Scala is only just beginning to reach a wide audience and
(b) due to (a), there is no business case for spending time on a Scala IDE.
Also, if you are old enough to cast your mind back and young enough to still remember, you would know that for the first five or more years of Java, we were stuck with okay-ish tools like JBuilder that did little more than compile your code when you said so - no error highlighting, no auto-importing, and the word refactoring didn't even exist. If you want to pioneer, you need to be prepared to cut some of the road yourself, or at least bush-bash.
I know it won't help you, but I have successfully used IDEA for Scala on Linux, Mac and Windows. I typically have the Scala SDK installed somewhere locally and point IDEA at that rather than using the 'download' option.
Presently, I am mostly using an EAP version of IDEA 9 on Mac OS X with Scala 2.8.0.Beta1-RC5 and it's working well (except that fsc doesn't seem to worked with mixed sources).
You could try your luck over at the IDEA Scala Plugin Discussion Forum, though I haven't had a great lot of responses to my own postings there.
Installing the plug-in is prerequisite one.
The next thing you should do is define a library (global or project-specific; I use global) that holds the Scala library and compiler JAR files (at a minimum, that's scala-compiler.jar and scala-library.jar). Adding source JARs and a documentation JAR or URLs is a good idea, too. Then make this library a dependency of any modules in your project that include Scala code.
Lastly, find the Scala facets in those modules and de-select both check-boxes there.
I just did a fresh install and had exactly this same problem myself.
It turned out that, because I had created the file in the root package, IDEA had added a package statement at the top with naming a package. I assume that this then got compiled as "package object Main" - valid syntax in 2.8? Anyway, I deleted the line that said package and it all worked fine.
I had the same problem yesterday while trying to set it up. Solution is pretty simple, you just have to set scala somewhere in project settings.
You are mixing code compiled with two different Scala versions.
I use Netbeans to write scala programs. So far it works very well with my codes. You can try the plugin here: http://wiki.netbeans.org/Scala68v1.
I was getting this error and also had to right click on the project and "Open Module Settings". However, it was more than just hitting apply. I had to make sure that my Content Root was correct for each project. For some reason, there were some incorrect Source and Test Folders.
My project uses maven as the main build tool and importing the project into Intellij is probably what created these incorrect settings.
I had similar problem, following this blog post instructions solved the problem for me
I downloaded the source code for the EMF based UML2 Plugin and changed a class in the org.eclipse.uml2.uml.edit project to remove special characters when returning string representations. Now when I export the projects and place the jar files either in the dropins directory or replace my current uml2 plugin jar files in plugins directory, The UML files are no longer recognized, in short my modified plugin does not install correctly (no error is thrown and I can see the files being picked up under Plugins->Target Platform) .
However, When I run the plugin as an eclipse application (from the workspace) I can see the changes I made being reflected in the new instance of eclipse.
What can I do to ensure that the plugin installs correctly?
Is there a documented procedure of how to build the uml2 plugin (or any comparable plugin) after modification?
Select the project and open the context menu. There is an entry PDE near the bottom of the menu. In there, you can find an entry to build the plugin for deployment. This gives you the features and plugins directory with the fixed files. Copy both into your Eclipse install.
Unless the UML2 plugins require some kind of magic build script, exporting the one plugin you changed and overwriting the original in your Eclipse installation should be the easiest solution. One potential problem which comes to mind is conflicting plugin version numbers: make sure you don't have two identical versions of your modified plugin in your Eclipse installation.
When debugging plugins which apparently don't work properly at runtime, I always look at Help > About Eclipse Platform > Configuration Details. This lists all the plugins found by Equinox during startup, along with their status (see the Javadoc of the org.osgi.framework.Bundle interface for explanation).
I faced the exact same problem as you describe here . I dont have any answer to your problem but i am sharing what worked for me .
I created a local update site of the plugin on my system. Create update site for your plug-in article explains very very nicely the steps needed to accomplish this .
