A good bit of stuff is hard coded, so if it works, it will need some changes before it'll be ready for actual use. After setup, hit the button and you should get some log entries from the driver. Screenshot and post those here.
I am upgrading a Spring MVC application from Java 1.8 to Java 17. I have tried to update the groovy version from 2.4.x to 3.0.15. If I run the clean build, either from IntelliJ terminal or Mac command prompt, the build runs, but if I refresh using the Gradle refresh image shown on the gradle file, there is an update and the build fails with the following exception:
In our project we have one workflow which relies on python numpy matrices to assign appropriate user. There is no issue with calling python from scriptrunner script and getting its value. However, the numpy matrix needs some calculated value to determine which user it will return, and that value is calculated by another script
The issue is, python matrix cannot call groovy script. It just returns an error stating it doesn't have necessary file permissions. All the groovy scripts, and groovy executable on the server were chmod 777 to see if it will help. It didn't.
While documentation says it should be possible for a groovy script executed with the .../bin/groovy should be able to return a final value, I wasn't able to get that behaviour either from a shell command line of from python Popen.
We don't want to run it through REST. Although you say that scriptrunner groovy engine can be accessed through it. Which means it has to be installed with plugin itself, is there any way to call it locally on jira itself? Any specific path to it maybe?
This chapter covers the syntax of the Groovy programming language.The grammar of the language derives from the Java grammar,but enhances it with specific constructs for Groovy, and allows certain simplifications.
Beside the single-line comment, there is a special line comment, often called the shebang line understood by UNIX systemswhich allows scripts to be run directly from the command-line, provided you have installed the Groovy distributionand the groovy command is available on the PATH.
Text literals are represented in the form of chain of characters called strings.Groovy lets you instantiate java.lang.String objects, as well as GStrings (groovy.lang.GString)which are also called interpolated strings in other programming languages.
If your code is indented, for example in the body of the method of a class, your string will contain the whitespace of the indentation.The Groovy Development Kit contains methods for stripping out the indentation with the String#stripIndent() method,and with the String#stripMargin() method that takes a delimiter character to identify the text to remove from the beginning of a string.
Any Groovy expression can be interpolated in all string literals, apart from single and triple-single-quoted strings.Interpolation is the act of replacing a placeholder in the string with its value upon evaluation of the string.The placeholder expressions are surrounded by $. The curly braces may be omitted for unambiguous dotted expressions,i.e. we can use just a $ prefix in those cases.If the GString is ever passed to a method taking a String, the expression value inside the placeholderis evaluated to its string representation (by calling toString() on that expression) and the resultingString is passed to the method.
When a method (whether implemented in Java or Groovy) expects a java.lang.String,but we pass a groovy.lang.GString instance,the toString() method of the GString is automatically and transparently called.
You can access elements of the list with the [] subscript operator (both for reading and setting values)with positive indices or negative indices to access elements from the end of the list, as well as with ranges,and use the
There are multiple advantages in using method pointers. First of all, the type of such a method pointer isa groovy.lang.Closure, so it can be used in any place a closure would be used. In particular, it is suitable toconvert an existing method for the needs of the strategy pattern:
Ranges implementation is lightweight, meaning that only the lower and upper bounds are stored. You can create a rangefrom any Comparable object that has next() and previous() methods to determine the next / previous item in the range.For example, you can create a range of characters this way:
In Groovy, using == to test equality is different from using the same operator in Java. In Groovy, it is calling equals.If you want to compare reference equality, you should use is like in the following example:
The diamond operator () is a syntactic sugar only operator added to support compatibility with the operator of thesame name in Java 7. It is used to indicate that generic types should be inferred from the declaration:
A simple import is an import statement where you fully define the class name along with the package. For example the import statement import groovy.xml.MarkupBuilder in the code below is a simple import which directly refers to a class inside a package.
Groovy, like Java, provides a special way to import all classes from a package using *, the so-called on-demand or star import. MarkupBuilder is a class which is in package groovy.xml, alongside another class called StreamingMarkupBuilder. In case you need to use both classes, you can do:
A groovy.lang.Script is always compiled into a class. The Groovy compiler will compile the class for you,with the body of the script copied into a run method. The previous example is therefore compiled as if it was thefollowing:
If the script is in a file, then the base name of the file is used to determine the name of the generated script class.In this example, if the name of the file is Main.groovy, then the script class is going to be Main.
if the variable is undeclared, it goes into the groovy.lang.Script#getBinding(). The binding isvisible from the methods, and is especially important if you use a script to interact with an application and need toshare data between the script and the application. Readers might refer to theintegration guide for more information.
Normal classes refer to classes which are top level and concrete. This means they can be instantiated without restrictions from any other classes or scripts. This way, they can only be public (even though the public keyword may be suppressed). Classes are instantiated by calling their constructors, using the new keyword, as in the following snippet.
Inheritance in Groovy resembles inheritance in Java.It provides a mechanism for a child class (or subclass) to reusecode or properties from a parent (or super class).Classes related through inheritance form an inheritance hierarchy.Common behavior and members are pushed up the hierarchy to reduce duplication.Specializations occur in child classes.
To create an object by using positional parameters, the respective class needs to declare one or moreconstructors. In the case of multiple constructors, each must have a unique type signature. The constructors can alsobe added to the class using the groovy.transform.TupleConstructor annotation.
If no (or a no-arg) constructor is declared, it is possible to create objects by passing parameters in the form of amap (property/value pairs). This can be in handy in cases where one wants to allow several combinations of parameters.Otherwise, by using traditional positional parameters it would be necessary to declare all possible constructors.Having a constructor where the first (and perhaps only) argument is a Map argument is also supported - such aconstructor may also be added using the groovy.transform.MapConstructor annotation.
Method selection then is about finding the closest fit from valid method candidates which have compatibleparameter types.So, method(Object, Object) is also valid for the first two invocations but is not as close a matchas the variants where types exactly match.To determine the closest fit, the runtime has a notion of the distance an actual argumenttype is away from the declared parameter type and tries to minimise the total distance across all parameters.
The JavaBeans specification makes a special case for properties which typically might be acronyms.If the first two letters of a property name are uppercase, no capitalization is performed(or more importantly, no decapitalization is done if generating the property name from the accessor method name).So, getURL would be the getter for a URL property.
In case this behavior is not the one you want, you can explicitly choose which method to call using the Trait.super.foo syntax.In the example above, we can ensure the method from trait A is invoked by writing this:
As the priority rules imply that LoggerHandler wins because it is declared last, then a call to on will usethe implementation from LoggingHandler. But the latter has a call to super, which means the next trait in thechain. Here, the next trait is DefaultHandler so both will be called:
In this example, when super.append is encountered, there is no other trait implemented by the target object, so themethod which is called is the original append method, that is to say the one from StringBuilder. The same trickis used for toString, so that the string representation of the proxy object which is generated delegates to thetoString of the StringBuilder instance.
It would allow us to dramatically reduce the boilerplate code, and reduces the risk of forgetting to change the setupcode in case we decide to change it. Even if setup is already implemented in the super class, since the test class declaresthe trait in its interface list, the behavior will be borrowed from the trait implementation!
The reason is that the sum method accesses the fields of the trait. So it is using the x and y values definedin the trait. If you want to use the values from the implementing class, then you need to dereference fields by usinggetters and setters, like in this last example:
It can be useful to make a copy of a record with some components changed.This can be done using an optional copyWith method which takes named arguments.Record components are set from the supplied arguments.For components not mentioned, a (shallow) copy of the original record component is used.Here is how you might use copyWith for the Fruit record:
