Creating custom JUnit launch configuration in eclipse [duplicate]

I am trying to write a custom launch configuration while running a plugin project as an eclipse application. I have to run the plugin with limited dependencies. Is it possible to override methods in org.eclipse.pde.launching.EclipseApplicationLaunchConfiguration ? If yes then how do I do it ?

You can't easily override the methods in EclipseApplicationLaunchConfiguration. That would require writing a new launch configuration - probably by using the org.eclipse.debug.core.launchConfigurationTypes extension point to define a new launch type.
EclipseApplicationLaunchConfiguration always uses the settings from the current entry in the 'Eclipse Application' section of the 'Run Configurations'. You can always edit the run configuration to change the dependencies or create another run configuration with different dependencies.

To write a custom configuration file
Extend the class org.eclipse.jdt.junit.launcher.JUnitLaunchShortcut
Override the method createLaunchConfiguration
Invoking super.createLaunchConfiguration(element) will return a ILaunchConfigurationWorkingCopy
Use the copy and set your own attributes that have to be modified
Attributes can be found in IPDELauncherConstants
Eclipse by default runs all the projects found in the workspace. This behavior can be modified by using the configuration created and overriding it with custom configuration.

DCM4CHE, Network operations,Handling a C-Move call

Hi I'm trying to make a PACS server using Java. dcm4che appears to be quite popular. But I'm unable to find any good examples about it.
As a starting point I inspected dcmqrscp and it successfully stores a DICOM image. But I cannot manage to handle a C-MOVE call. Here's my CMove handler. It finds requested the DICOM file adds a URL and other stuff, it doesn't throw any exception yet client doesn't receive any files.

You should add a role to the application instance like:

new TransferCapability(null, "*", TransferCapability.Role.SCP, "*"));

Upload file to existing Google Drive Folder - Android

I want to upload a file to an existing Google Drive folder.
I am using this how to upload an image from my android app to a specific folder on google drive to get the folder name but not sure how to implement it (smokybob's answer)
//Search by name and type folder
String qStr = "mimeType = 'application/vnd.google-apps.folder' and title = 'myFolder'";
//Get the list of Folders
FileList fList=service.files().list().setQ(qStr).execute();
//Check that the result is one folder
File folder;
if (fList.getItems().lenght==0){
folder=fList.getItems()[0];
}
//Create the insert request is as in the sample
File file = service.files().insert(body, mediaContent);
//set the parent
file.setParents(Arrays.asList(newParentReference().setId(folder.getFolderId())));
//execute the request
file.execute();
I am getting cannot resolve symbol errors for FileList, body, mediacontent.
I am getting cannot resolve method for .files, getitems(), setparents, newparentsreference, and execute.

This ID is used in subsequent calls as a "parent ID". If you have questions about unresolved methods, please refer to this GitHub project.

Good Luck

how to write equivalent java code to "git diff tag1 tag2 --some/file/path"

I try to implement the function like following:
public List<RevCommit> createFileHistoryFromTag(File file, String fromTag,
String toTag) {
Iterable<RevCommit> commits = null;
try {
List<Ref> refs = git.tagList().call();
ObjectId fromTagId = null;
ObjectId toTagId = null;
for (Ref refTag : refs) {
if (refTag.getName().equals(fromTag)) {
fromTagId = refTag.getObjectId();
} else if (refTag.getName().equals(toTag)) {
toTagId = refTag.getObjectId();
}
}
if (fromTagId == null) {
throw new RuntimeException("Couldn't resolve fromTag: "
+ fromTag + " Make sure you gave an existing ref");
}
if (toTagId == null) {
throw new RuntimeException("Couldn't resolve toCommit: "
+ toTag + " Make sure you gave an existing ref");
}
commits = getCommitListFromTagForFile(file.getAbsolutePath()
.substring(1), fromTagId, toTagId);
} catch (GitAPIException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return Lists.newArrayList(commits);
}
and the geCommitListFromTagForFile like following:
private RevCommitList<RevCommit> getCommitListFromTagForFile(String path,
ObjectId start, ObjectId end) throws IOException {
RevWalk revisionWalk = buildRevisionWalk(path, start, end);
final RevCommitList<RevCommit> list = new RevCommitList<>();
list.source(revisionWalk);
list.fillTo(Integer.MAX_VALUE);
return list;
}
finally buildRevisionWalk function
private RevWalk buildRevisionWalk(String path, ObjectId start, ObjectId end)
throws IOException {
Config config = new Config(git.getRepository().getConfig());
config.setString("diff", null, "renames", "copies");
config.setInt("diff", null, "renameLimit", Integer.MAX_VALUE);
DiffConfig diffConfig = config.get(DiffConfig.KEY);
final RevWalk revisionWalk = new RevWalk(git.getRepository());
revisionWalk.setTreeFilter(FollowFilter.create(path, diffConfig));
revisionWalk.markStart(revisionWalk.parseCommit(start));
if (end != null) {
revisionWalk.markUninteresting(revisionWalk.parseCommit(end));
}
return revisionWalk;
}
But it won't return any commit message, if one file between two tags is changed.
Basically I want the functionality like
git diff v.4.32b759 v4.32b760 --some/file/path
and get the commit message from this tag

Elasticsearch: Adding manual mapping using Java

I cant change the mapping. Can anybody help me to find the bug in my code?
I have found this standard way to change the mapping according to several tutorials. But when i'm try to call the mapping structure there just appear a blank mapping structure after manuall mapping creation.
But after inserting some data there appear the mapping specification because ES is using of course the default one. To be more specific see the code below.
public class ElasticTest {
private String dbname = "ElasticSearch";
private String index = "indextest";
private String type = "table";
private Client client = null;
private Node node = null;

}
public static void main(String[] args)
{
new ElasticTest();
}
}
I just wanna change the property of ATTR1 field to analyzed to ensure fast queries.
What im doing wrong? I also tried to create the mapping after index creation but it leads to the same affect.

Ok i found the answer by my own. On the type level i had to wrap the "properties" with the type name. E.g:
"type1" : {
"properties" : {
.....
}
}
See the following code:
private XContentBuilder getMappingsByJson(){
XContentBuilder builder = null;
try {
builder = XContentFactory.jsonBuilder().startObject().startObject(type).startObject("properties");
for(int i = 1; i<5; i++){
builder.startObject("ATTR" + i)
.field("type", "integer")
.field("store", "yes")
.field("index", "analyzed")
.endObject();
}
builder.endObject().endObject().endObject();
}
catch (IOException e) {
e.printStackTrace();
}
return builder;
}
It creates mappings for the attributes ATTR1 - ATTR4. Now it is possible to define mapping for Example a list of different attributes dynamically. Hope it helps someone else.
