How can I pass arguments to an extension point constructor/ createExecutableExtension with parameters in eclipse

Please also refer to my previous post.
http://exploreeclipse.blogspot.in/2015/09/reading-extension-point-from-eclipse.html

public void readExtensionPoint(String myjsonString) {

IExtensionRegistry registry = Platform.getExtensionRegistry();

IConfigurationElement[] elements = registry.getConfigurationElementsFor("com.kk.myplugin", "services");

for (IConfigurationElement iConfigurationElement : elements)

{

iConfigurationElement.getAttribute("service_id");

iConfigurationElement.getAttribute("name");

try

{

try

{

String attribute = iConfigurationElement.getAttribute("class");

String contributorName = iConfigurationElement.getDeclaringExtension().getContributor().getName();

Class<?> javaClass = Platform.getBundle(contributorName).loadClass(attribute);

Constructor<?> ctor = javaClass.getDeclaredConstructor(String.class);

IService service = (IService) ctor.newInstance(myjsonString);

return service;

}

catch (Exception e)

{

}

}

catch (CoreException e)

{

e.printStackTrace();

}

}

}

Reading an extension point from eclipse plugin

public void readExtensionPoint() {

IExtensionRegistry registry = Platform.getExtensionRegistry();

IConfigurationElement[] elements = registry.getConfigurationElementsFor("com.kk.core", "platformServices");

for (IConfigurationElement iConfigurationElement : elements)

{

iConfigurationElement.getAttribute("id");

try

{

//This is your class

Object createExecutableExtension = iConfigurationElement.createExecutableExtension("class");

}

catch (CoreException e)

{

e.printStackTrace();

}

}

}

Storing in eclipse secure storage with encryption

ISecurePreferences root = SecurePreferencesFactory.getDefault();

ISecurePreferences node = root.node("/com/kk/store"); //path

//store

try

{

node.put("myusername", "mysecretpassword", true);

}

catch (StorageException e)

{

e.printStackTrace();

}

Where does Eclipse secure storage file is saved ?

This you can find from Eclipse preferences.
Eclipse -> Preferences -> General -> Security -> Secure Storage -> Contents Tab

Here you can find 'Storage Location'.

Example:
/Users/kkolipaka/.eclipse/org.eclipse.equinox.security/secure_storage

How to get the Eclipse Installation location ?

Eclipse provided a direct API call for this.

Platform.getInstallLocation().getURL();

To get a string path:

Platform.getInstallLocation().getURL().getPath();

Undo a git rebase

Step 1: Identify the head commit of the branch till where you wanted to undo it.

$ git reflog

5621e87 HEAD@{0}: checkout: moving from TISTUD-7562 to development

7747926 HEAD@{1}: rebase -i (finish): returning to refs/heads/TISTUD-7562

7747926 HEAD@{2}: rebase -i (squash): TISTUD-7562:For limited plan billing is not opened via wizard

2101ed5 HEAD@{3}: rebase -i (start): checkout 5621e87fac883fca1783bb2f1b6f811422bdf289

0975830 HEAD@{4}: rebase: aborting

0975830 HEAD@{5}: reset: moving to HEAD@{1}

2101ed5 HEAD@{6}: rebase -i (start): checkout 5621e87fac883fca1783bb2f1b6f811422bdf289

0975830 HEAD@{7}: commit: TISTUD-7562:Avoiding multiple validations during the package launch actions from package explorer and app explorer.

2101ed5 HEAD@{8}: rebase finished: returning to refs/heads/TISTUD-7562

2101ed5 HEAD@{9}: rebase: TISTUD-7562:For limited plan billing is not opened via wizard

Here, I wanted to undo till HEAD@{7}

Step 2: Reset to required commit

$ git reset --hard HEAD@{7}

This will bring back all the changes which you are having at HEAD@{7} commit.
