i`m actually working for a tool, which counts the methods in a class and the number of the if statements. the purpose is to estimate the quantity of test cases to write.
I've noticed that the Eclipse outline box has some interesting information and it would be really nice to get the code which produces the outline information.
I`ve already browsed through the Eclipse Git site, but I am a beginner and there are so many packages, can anybody tell me where I can find the source code for the Outline view, or point me in a good direction?
Best regards.
Download Eclipse Classic which contains the source code for Eclipse. It also allows you to sniff which packages are being used by Eclipse using the plugin-spy. You can then import the specific package and set debug points within it to view the source being executed when a specific event occurs.
The following article provides a good tutorial on the steps mentioned above:
Eclipse Source Code Tutorial
See this article about how to access the Java model from your plugin. IJavaProject is the relevant API.

I would like to write small eclipse plugin for code estimation. At start I would like to use results shown in "problems" tab (warnings and errors) instead of writing next, own tool for code analysis. The question is:
Is it possible to use data from one plugin in another?
I would be greatful for any examples or links to tutorials.
Thank you in advance :)
The objects in the Problems view are called 'markers' and are represented by the org.eclipse.core.resources.IMarker interface.
You get the markers defined on a file, folder or project by calling the findMarkers method on the IResource. You can ask for all types of marker or just specific types.
I have a question about generating sequence diagram from Java source code. When I googled I saw someone told to use visual paradigm (VP), but it does not generate sequence diagram for me. Some steps in my VP are different from manual. The manual says to choose method but my VP does not allow to select method in a special class. Reverse Engineering Sequence Diagram from Java Source Code
Does anyone have a new idea to generate sequence diagram from Java source code?
With Intellij 2019 there are two plugins can do this job:
SequenceDiagram (currently 1.3).
Go in your in Class method that you want to analyse and Tool>SequenceDiagram :
ZenUML support (currently 2019.1.2)
If you are using or wish to use the Eclipse IDE then you can install the ObjectAid UML plugin that can reverse engineer from:
Java Stack Trace Console
Java Stack Frames from Debug View
Methods Call from Call Hierarchy View
and MUCH more.
See http://www.objectaid.com/sequence-diagram
I have implemented a junit test based sequence generator which generates sequence diagrams for the pgf-umlsd latex package example:
Hello world
#Test
#SequenceDiagram({ Controller.class, Model.class })
public void testMethod() {
Controller c = new Controller(new Model());
c.init();
c.simpleBeanOperation();
}

try this tool, This tool helps you to create the Java source code to Sequence and class diagram, including the execution time of each flow.
follow the steps as given in the documentation
http://maintainj.com/
UML-VP could generate sequence diagrams, pretty well. Based on your description, I feel you chose the package directory for presenting the source files to the tool. I have faced similar problem. The solution is to choose the "src" folder above the package folder, and then you can see some pretty nice diagrams flying out. Good Luck.
I used Umlgraph which is free see http://www.umlgraph.org/
But I mostly use it to generate class diagram in Javadoc.
To generate sequence diagram, you have to write many lines in your source file.
See http://www.umlgraph.org/doc/dns.html.
You will have to install Graphviz to make it work.
Another good tool that generates sequence diagrams from Java programs is JIVE: www.cse.buffalo.edu/jive
It is available as a plug-in for Eclipse and is a free download. Also supports visualization of multi-threaded Java programs.
Note: JIVE generates the diagram for the execution of the program. It also generates object diagrams, and has other useful features such as query-based debugging. Sorry if this is not what you had in mind.
I tried a lot of options today to generate Sequence and class diagrams from my existing code using IntelliJ Idea community edition, Below is the Solution which worked for me finally:
Specific versions of Intellij community edition only was compatible with the required plugins to make this work.
so its very important to download the right versions of IDE and plugins to make it work.
Here are the links to the complete set of softwares with specific versions which worked for me, pls note i tested these on my Mac Book Pro:
[IntelliJ Community Edition IDE]
Code Iris for creating class diagrams and visualizing the code
SequenceDiagram Plugin for generating Seq Diagram on IntelliJ
IDE.
There are many products that can generate sequence diagrams from Java source code. Unfortunately, all of the good ones cost a lot of money.
If you are using the community edition of Visual Paradigm, it does not allow you to generate any diagrams. You must upgrade to one of the paid versions.
You can compare the paid vs the free edition here
http://www.visual-paradigm.com/product/vpuml/features/?edition=ce
You need to buy standard edition of Visual Paradigm that support Code engineering.
Check out some of these links for alternative programs which also can generate diagrams / source code.

How can I generate sequence diagrams from Java source code?
Sequence Diagram Reverse Engineering
http://www.altova.com/umodel/sequence-diagrams.html
The unable to select operation when performing reverse engineering of Java source code to sequence diagram in VP probably caused by selecting the wrong source folder. As long as you select the root folder of your source (according to the "package" statement of your class) it should then works. BTW, Visual Paradigm offer the subscription license which allow user to subscribe the license in monthly basis and in a relative low cost.
I've found LINQPad to be extremely useful when answering StackOverflow questions for C# or VB.NET. It allows me to write up some quick code, run it, and (if I want) see a nicely-formatted dump of the results. That way I can be sure that the code I post actually runs. Thus far I haven't seen anything that I can use to achieve the same result with Java. Is there anything like that out there?
I am not looking for something to query data sources; I just want a light-weight IDE. These are the features I'm particularly interested in:
The ability to write and run short snippets of code without establishing a whole project or file structure.
Reporting of compiler and runtime errors in the code when it is run.
The ability to add references to a particular editor instance.
Syntax highlighting and Autocomplete/Intellisense would be a plus.
JPad - A java scratchpad for running snippets
Since I also couldn't find one I've decided to write one. Currently it can:
Run java snippets (no class / imports / public blah... needed).
Contains drivers for MS/MySQL/Postgres.
Output results as HTML tables
It's very rough but I will add to it over time. Feedback is definitely welcome.
This may help : http://www.browxy.com:9000/codeRunner
EDIT: Url seems to have changed to http://www.browxy.com
You can use the Groovy web console ; it's possible to speak java in groovy land.
Java Snippet Runner:
Does something similar to Linqpad (jar file, not just for macs)
http://mac.softpedia.com/get/Development/Java/Java-Snippet-Runner.shtml
Code Runner (Commercial):
for Mac's only, it'll run code snippets in Java, and lots of other languages too (e.g. Objective C)
http://krillapps.com/coderunner/
http://ideone.com is an online service that has the features you want.
I've been using JEdit for a long time, which is a very powerful cross-platform editor, NOT an IDE. It does have plugins to execute Java code right in the editor, and even uses BSH for macros.
I was looking for a "Java LinqPad" also, and i came across :
this
I've been using IntelliJ IDEA and it works really well as a Groovy scratchpad. The Community Edition is free too.
You need to create a new project, but then can add Groovy scripts to it and run them on the fly. Not had any luck with the actual Scratch File functionality though.
Being a Jetbrains editor it's pretty slick too. (Unlike some of the other options)
Nothing beats LinqPad though.
I have a maven project imported into Eclipse. I'm trying to understand the code pattern (architecture). What is the best way to do this?
will use any UML Eclipse plugin help on this?
will use sequence diagram, help on this?
what plugins should I use?
Please share your opinion.
When I am working with a open source project/codebase I get a high-level view and focus on the core code/logic by checking the package names and structure. I then typically determine how the API works by looking at any example code / documentation contained in the project. If I still need some more help I will draw up some inheritance diagrams, print out interesting classes that I may need to make significant changes to, and try to find more examples of the code being used elsewhere.
I am biased and have been using our recently launched Architexa Eclipse plugin to accomplish the above. I am sure there are others available that do something similar.
I guess you will find some pointers in this SE-Radio podcast: Episode 148: Software Archaeology with Dave Thomas.
Of course, UML can help, but on the other side, it might not as well. For reverse engineering, there is the MoDisco project in Eclipse, which might be useful.
I am working on an incremental builder for Java code in Eclipse. Eclipse provides a ResourceDelta that tells me which resources have changed since the last build. However, I would like to have more detailed information, e.g. what methods or what field definitions changed. There seems to be functionality similar to what I want in the "compare with -> each other" view. However, this code is quite disconnected from the build engine and seems incompatible with ResourceDeltas. What would be a good way to figure out what I want? The best solution I can see is to compare two ASTs, but I also could not find any built-in support for that.
JavaCore does supply this information via the IElementChangedListener and IJavaElementDelta interfaces. Here's a quick code sample to get you started:
JavaCore.addElementChangedListener(new MyJavaElementChangeReporter(), ElementChangedEvent.POST_RECONCILE);
