I am trying to add tests using latest (5.7.0) Mockito and using Mockito.mockStatic(...)
to mock class with static methods which works fine . However when I have class with static block it is unable to create mock and fais with java.lang.InternalError: class redefinition failed: invalid class .
Is this supported in latest mockito versions or still I have to live with other alternatives like powermock.
I did face the same error and couldn't find answer in the internet, so I see that it is 1 month old question but might help someone.
The problem was that mocked class (or classes that this static block used) was not in the classpath. Before you can mock the method all static blocks or fields initializators will be run, and it causes the problem.
You can verify what class is missing in your classpath by simply trying to use this static method before mocking it. You should get java.lang.NoClassDefFoundError with a class name.
When you resolve this problem, everything should work.
I had this issue, and for me it was due to an Error being thrown from instrumentation.retransformClasses called from org.mockito.internal.creation.bytebuddy.inlineBytecodeGenerator. Somewhere between there and findOrInsert in net.bytebuddy.TypeCache, the Throwable looses its context (for mockito-core 4.1.0 and bytebuddy 1.12.0)
In my case, the error being thrown was a NoClassDefFoundError for Jetty Servlet. This ultimately turned out to be a dodgy local build of a different maven module I had been working on, so clearing out my ~/.m2 and downloading a legit version fixed that right up.
You might be able to catch the Error being thrown in inlineBytecodeGenerator and taking a look at what's really going on, if this is in fact the same problem.

I have a set of code procedures I use in a lot of places and I'm trying to basically move it to a library.
So I created my library with some unit test and everything was looking promising and at least working localy..
When I went to my project and deleted the files locally and then try to import them from my library as a dependency the code does not work.
I always get this kind of error
Class does not define or inherit an implementation of the resolved method abstract getProperty(Ljava/lang/String;)Ljava/lang/Object; of interface groovy.lang.GroovyObject.
I'm definitely not an expert on groovy but basically I use it in my Jenkins and Gradle for pipelines and some basic packaging or environment deployments.
I can show my class:
class ConsoleRow implements Comparable {
...
final Integer priority
final String rowStatus
final String message
final String rowReportClass
ConsoleRow(Integer priority, String status, String msg, String rowC) {
this.priority = priority
this.rowStatus = status
this.message = msg
this.rowReportClass = rowC
}
#Override
int compareTo(Object o) {
return this.priority <=> ((ConsoleRow) o).priority
}
The line that gives me the error is this actual compareTo when trying to do the "this.priority"
Caused by: java.lang.AbstractMethodError: Receiver class com.abc.insight.jenkins.ConsoleRow does not define or inherit an implementation of the resolved method abstract getProperty(Ljava/lang/String;)Ljava/lang/Object; of interface groovy.lang.GroovyObject.
at com.abc.insight.jenkins.ConsoleRow.compareTo(ConsoleRow.groovy:24)
at com.abc.insight.jenkins.ConsoleOutputHtmlBuilder.processOutput(ConsoleOutputHtmlBuilder.groovy:115)
at com.abc.insight.jenkins.ConsoleOutputHtmlBuilder.processOutput(ConsoleOutputHtmlBuilder.groovy)
at com.abc.insight.jenkins.ConsoleOutputHtmlBuilder.buildReport(ConsoleOutputHtmlBuilder.groovy:20)
at com.abc.insight.jenkins.ConsoleOutputHtmlBuilder$buildReport.call(Unknown Source)
at build_e548mc0tqjmi822clitlsycdk.runReport(C:\dev\repo\insight\insight-health-check\data-foundation\smoke-test\build.gradle:77)
The calling function is just trying to sort a list of those objects
List<ConsoleRow> outputRows = []
...
return outputRows.sort()
The part that gets me really confused is that if instead of importing the library as a dependency I just do this directly in this repo and put my sources in my buildSrc\src\main\groovy\com\abc\insight the code works fine...
So I really think it might be how I package and publish my library that might be wrong.
I'm really sure this is some basic error on my part because I never did a groovy library before but somehow I can't make it work.
It might be that my publication is just wrong, on my library side I'm using this plugins to do the publishing.
plugins {
id 'groovy'
id 'java-library'
id 'base'
}
publishing {
publications {
maven(MavenPublication) {
from components.java
}
}
}
I tried to change components.groovy but somehow it does not work.
Any ideas or tips, I think my question probably is showing some really lack of know-how on groovy but looking at the documentation and examples I could not figure it out.
Doing some debug in my IDE the compareTo that generates the exception looks like this.
public int compareTo(Object o) {
CallSite[] var2 = $getCallSiteArray();
return ScriptBytecodeAdapter.compareTo(this.priority, var2[0].callGroovyObjectGetProperty((ConsoleRow)ScriptBytecodeAdapter.castToType(o, ConsoleRow.class)));
}
I tried following this guide and code structure when doing moving the code to a library
https://docs.gradle.org/current/samples/sample_building_groovy_libraries.html
Thanks for any feedback
p.s: My code might look weird, I tried first to have everything with the def blablabla but I was having some issues with typecasting but I don't think this would be the reason for the problem I'm facing.
Anyway I got a look at the generated code in my IDE and I see a lot of get methods just no idea where they expected this getProperty from
Ok this was definitely a user error.
I am using distribution version of gradle 6.5.1
When I did the gradle init to bootstrap my project I was provided with the dependency of gradle groovy-all version 2.5.11
implementation group: 'org.codehaus.groovy', name: 'groovy-all', version: '2.5.11'
I thought that was a mistake and just updated to the latest version.
implementation group: 'org.codehaus.groovy', name: 'groovy-all', version: '3.0.9'
Now the problem is that the project in which I'm using the library is also running with gradle 6.5.1 so probably this version missmatch between compiple and usage was causing the problem.
By reverting to the correct version suggested by gradle the problem is gone.
We have been building our application using groovy 2.3.6. Now because of some platform level issues we are advised to downgrade our groovy version to 2.2.1. I am facing no. of issues regarding this downgrade.
groovy is not able to infer the type of it variable in ver 2.2.1 so if i have code something like this
names.any { sliceName.endsWith(it) }
it gives me exception
[Static type checking] - Cannot find matching method java.lang.String#endsWith(java.lang.Object)
Secondly all the default method that i had used in collections no longer seem to exist
positions.any { it.primary }
groovy is unable to find the any method on list.
One way would be turn off static type checking, which will expose the code to a lot more runtime errors.
Is there any way to resolve these errors, without turning off static type checking. Also are these features only added in groovy 2.3.6 like default groovy methods and type inference for it variable
If you go back to an old version, old bugs will bite you.
Try giving the static compiler more of a hint
names.any { String it -> sliceName.endsWith(it) }
I'm in the process of trying to migrate a R# extension project from R# 6 to R# 8. (I've taken over a project that someone wrote, and I'm new to writing extensions.)
In the existing v6 project there is a class that derives from RenameWorkflow, and the constructor used to look like this;
public class RenameStepWorkflow : RenameWorkflow
{
public RenameStepWorkflow(ISolution Solution, string ActionId)
: base(Solution, ActionId)
{
}
This used to work in R# SDK v 6, but now in V8, RenameWorkflow no longer has a constructor that takes Solution and actionId. The new constructor signature now looks like this;
public RenameWorkflow(
IShellLocks locks,
SearchDomainFactory searchDomainFactory,
RenameRefactoringService renameRefactoringService,
ISolution solution,
string actionId);
now heres my problem that I need help with (I think)
I've copied the constructor, and now the constructor of this class has to satisfy these new dependancies. Through some digging I've managed to find a way to satisfy all the dependencies, except for 'SearchDomainFactory'. The closest I can come to instantiating via the updated constructor is as follows;
new RenameStepWorkflow(Solution.Locks, JetBrains.ReSharper.Psi.Search.SearchDomainFactory.Instance, RenameRefactoringService.Instance, this.Solution, null)
All looks good, except that JetBrains.ReSharper.Psi.Search.SearchDomainFactory.Instance is marked as Obsolete, and gives me a compile error that I cannot work around, even using #pragma does not allow me to compile the code. The exact error message I get when I compile is Error 16 'JetBrains.ReSharper.Psi.Search.SearchDomainFactory.Instance' is obsolete: 'Inject me!'
Obvious next question..ok, how? How do I 'inject you'? I cannot find any documentation over this new breaking change, in fact, I cannot find any documentation (or sample projects) that even mentions DrivenRefactoringWorkflow or RenameWorkflow, (the classes that now require the new SearchDomainFactory), or any information on SearchDomainFactory.Instance suddenly now obsolete and how to satisfy the need to 'inject' it.
Any help would be most appreciated! Thank you,
regards
Alan
ReSharper has its own IoC container, which is responsible for creating instances of classes, and "injecting" dependencies as constructor parameters. Classes marked with attributes such as [ShellComponent] or [SolutionComponent] are handled by the container, created when the application starts or a solution is loaded, respectively.
Dependencies should be injected as constructor parameters, rather than using methods like GetComponent<TDependency> or static Instance properties, as this allows the container to control dependency lifetime, and ensure you're depending on appropriate components, and not creating leaks - a shell component cannot depend on a solution component for instance, it won't exist when the shell component is being created.
ReSharper introduced the IoC container a few releases ago, and a large proportion of the codebase has been updated to use it correctly, but there are a few hold-outs, where things are still done in a less than ideal manner - static Instance properties and calls to GetComponent. This is what you've encountered. You should be able to get an instance of SearchDomainFactory by putting it as a constructor parameter in your component.
You can find out more about the Component Model (the IoC container and related functionality) in the devguide: https://www.jetbrains.com/resharper/devguide/Platform/ComponentModel.html
I am trying to use org.xhtmlrenderer:core-renderer:R8pre2 in a groovy script, but I get a Linkage error:
Caught: java.lang.LinkageError: loader constraint violation in interface
itable initialization: when resolving method
"org.apache.xerces.dom.NodeImpl.getOwnerDocument()Lorg/w3c/dom/Document;"
the class loader (instance of org/codehaus/groovy/tools/RootLoader) of the
current class, org/apache/xerces/dom/NodeImpl, and the class loader (instance of
<bootloader>) for interface org/w3c/dom/Node have different Class objects for
the type getOwnerDocument used in the signature
I've already googled a lot and found a lot of answer like these:
Dealing with "Xerces hell" in Java/Maven?
XercesImpl in conflict with JavaSE 6's internal xerces implementation. Both are needed... what can be done?
So, one solution could be to use javas endorsed mechanism to resolve the conflict, but I would like to make my script independent from such a "workaround". The script should run out of the box.
Next thing I was giving a try was to exclude the right dependency like this
#Grapes([
#Grab('org.xhtmlrenderer:core-renderer:R8pre2'),
#GrabExclude('xml-apis:xml-apis')
])
but didn't succeed...
Any ideas?
PS: here is the script which creates the error:
#Grapes([
#Grab('org.xhtmlrenderer:core-renderer:R8pre2'),
])
import org.w3c.dom.Document
import javax.xml.parsers.DocumentBuilder
import javax.xml.parsers.DocumentBuilderFactory
def dbf = DocumentBuilderFactory.newInstance()
DocumentBuilder builder = dbf.newDocumentBuilder()
Document doc = builder.parse(new ByteArrayInputStream("<html></html>".getBytes()))
Thanx to #dmahapatro, I checked my configuration and found that I dropped some jars in {usrhome}/.groovy a long time ago. Removed these and now everything work like a charm...
I am continuously facing a situation of which I have no idea. I am tried to test one method that I have implemented in C++. I got an error, a Class init failed when calling newInstance .
It further states that cannot load library:reloc_library[1311]:33 cannot locate 'Z13trainFacePKcS0'... and suddenly it crashes and throw exception. It gives the same error. I will appreciate any help.
Regards,
Adonis.
You have loaded a library like this in the class which gets loaded during class initialization.
static {
System.loadLibrary("gamescript");
}
From your error you have posted, it seems the library cannot be located which means, it either is not present in the apk file or it is not inside the libs folder.
