Jenkins Execute shell commands with wildcards

I am trying to get Jenkins to execute a shell command but still allow wildcards to be used. Here's what I'm trying to do for reference: mvn deploy:deploy-file -Dpackaging=jar...

If you mean you just want the * to be passed on directly, just use single quotes to avoid the shell from applying globbing: mvn deploy:deploy-file [...] '-Dfile=Spigot/Spigot-Server/target/spigot-*.jar' more 4/16/2016 8:39:50 AM

Set and get properties and constants differences

Is there any difference between the following declarations (other than the difference between the const and static readonly)? public static int foo1 { get; } = 8; private static...

It's the same as foo2. The difference with foo3 is that the property access won't even consult foo3 - Foo3 is compiled to code equivalent to public static int Foo3 { { get { return 9; } } } Now admittedly from the perspective of... more 4/15/2016 7:32:31 PM

why? error? 'Car'member names cannot be the same as their enclosing type

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace half_test { class Car { private int...

Why? That's just the rules of the language. If you're creating a class called Car, it can't contain any members (properties, methods, fields, nested types, events) called Car. It would be really confusing if this were allowed,... more 4/15/2016 11:02:28 AM

I have the LocalDateTime with established timezone systemDefault No, you don't. You started with a LocalDateTime, but then you converted it into a ZonedDateTime. A ZonedDateTime is effectively a LocalDateTime with a ZoneId and an... more 4/14/2016 6:00:11 PM

Check subclass of an object in Java

Consider the classes MinorClassA and MinorClassB, both extending MajorClass. I have an object of MajorClass that I know for sure is actually an instance of one of its...

Sounds like you want the instanceof operator: At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a... more 4/14/2016 10:24:46 AM

Fixing an line in c# wpf

the line i got the error : IEnumerator enumerator = this.ListBox1.Items.GetEnumerator(); while (enumerator.MoveNext()) { object objectValue =...

The simplest fix would be to use the language support for iterators: foreach (object value in ListBox1.Items) { list2.Add(Conversions.ToString(value)); } If you expect the values to already be strings, you could make the foreach... more 4/14/2016 9:54:06 AM

Create xml attribute with namespace programatically

How can I create the following as XElement? <data name="MyKey" xml:space="preserve"> <value>Date of birth</value> <comment>Some...

Separate the namespace from the local name, using the XName +(XNamespace, string) operator for convenience: data.Add(new XAttribute(XNamespace.Xml + "space", "preserve")); Note that you can write the whole of your element creation in a... more 4/14/2016 8:53:45 AM

Tricky : Array of controls dynamically created causing problems

I put "Tricky" in the title because I'm aware that it will be hard to understand precisely what I want but I'll try to be clear. I have a textBox with an event for TextChange...

You need to do three things when the number changes: Remove any existing textboxes Create a new array with the new size, and save a reference to that new array into your field (textBoxesQ) Initialize the array So something like: if... more 4/14/2016 6:14:21 AM

How to Parse the first Property even if the Json is not valid?

I am parsing tons of different jsons which only have the first Property in common. Depending on the value of this first property I parse the json into different object and also...

You can use a JsonReader (probably JsonTextReader as the concrete type) to parse the JSON as a stream, a bit like XmlReader. So for example: using System; using System.IO; using Newtonsoft.Json; public class Test { static void... more 4/13/2016 3:02:56 PM

Property file same key with different value in java

I have a property file like this. host=192.168.1.1 port=8060 host=192.168.1.2 port=8070 host=192.168.1.3 port=8080 host=192.168.1.4 port=8090 Now I want the unique url so I can...

Basically that property file is broken. A property file is a sequence of key/value pairs which is build into a map, so it requires the keys be unique. I suspect that if you load this into a Properties object at the moment, you'll get just... more 4/13/2016 12:36:58 PM
