Standard Method TEXT is undefined when compiling jasper report

When I package my stand-alone-java-application, that compiles, renders and prints Jasper-Reports, in a fat jar with all dependencies, I get the error that the function TEXT – a function used in the report and defined in the net.sf.jasperreports-functions-library is not found.
The method TEXT(Integer, String) is undefined for the type [...]
value = IF(LEN(TEXT(((java.lang.Integer)parameter_X.getValue()),"#"))==2,"***",REPT("*",6-LEN(TEXT(((java.lang.Integer)parameter_X.getValue()),"#")))) //$JR_EXPR_ID=58$
Other functions from the same library work. When I run the application with gradle run, the function is found and the report can be printed. The library is on my classpath.
There are several similar questions on this site and Stackoverflow, but neither provided answers, that worked for me. In the following, I will explain what I tried:
In my build.gradle-File I defined dependencies to the following libraries:
implementation('net.sf.jasperreports:jasperreports:6.18.1')
implementation('net.sf.jasperreports:jasperreports-functions:6.18.1')
In my java-Files, I created a DesignFile and statically imported the functions into it. I tried two methods:
Method 1 as given in an answer in this thread: Unresolved symbols when compiling jasper report
/*…*/
designFile = JRXmlLoader.load(sourceFile.getAbsolutePath());
designFile.addImport("static net.sf.jasperreports.functions.standard.TextFunctions.*");
designFile.addImport("static net.sf.jasperreports.functions.standard.MathFunctions.*");
designFile.addImport("static net.sf.jasperreports.functions.standard.DateTimeFunctions.*");
designFile.addImport("static net.sf.jasperreports.functions.standard.LogicalFunctions.*");
JasperReport compiledReport = JasperCompileManager.getInstance(ctx).compile(designFile);
/*…*/
Method 2: importing each function on its own
public static String[] textFunctions(){
return new String[]{"BASE", "CHAR", "CLEAN", "CODE", "CONCATENATE", "DOUBLE_VALUE",
"EXACT", "FIND", /*"FIXED", */"FLOAT_VALUE", "INTEGER_VALUE", "LEFT", "LEN", "LONG_VALUE",
"LOWER", "LTRIM", "MID", "PROPER", "REPLACE", "REPT", "RIGHT", "RTRIM", "SEARCH", "SUBSTITUTE",
"T", /*"TEXT",*/ "TRIM", "UPPER"};
}}
/*…*/
designFile = JRXmlLoader.load(sourceFile.getAbsolutePath());
for (String textFunction : textFunctions()){
designFile.addImport("static net.sf.jasperreports.functions.standard.TextFunctions." + textFunction);
}/* similarly for logical functions, numeric functions and datetime functions*/
}
JasperReport compiledReport = JasperCompileManager.getInstance(ctx).compile(designFile);
/*…*/
As you can see, the function TEXT is commented out. That’s because the program fails at runtime when run with “gradle run”, when I comment it in:
net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:
1. The import net.sf.jasperreports.functions.standard.TextFunctions.TEXT cannot be resolved
import static net.sf.jasperreports.functions.standard.TextFunctions.TEXT;
The same thing is true with most datetime-functions, in fact, only TIME can be imported to the DesignObject without error at runtime
In addition to that, when I type net.sf.jasperreports.functions.standard.TextFunctions. in my IDE, the content-assist shows a list of available functions, yet TEXT is missing.
I suspected, that the function is simply missing in the library, but it is there. In the .gradle/cache/modules-2/files-2.1/… directory, there is the jar with the TextFunctions.java, that contains the function TEXT:
When building the FatJar with dependencies, I have a TextFunctions.class-File in it, that contains the TEXT-Function as well.
In my jar, there are two jasperreports_extension.properties on the root level:
with the smaller one (from the jasperreport-functions-dependency) containing the following lines:
net.sf.jasperreports.extension.registry.factory.functions=net.sf.jasperreports.functions.FunctionsRegistryFactory
net.sf.jasperreports.extension.functions.datetime=net.sf.jasperreports.functions.standard.DateTimeFunctions
net.sf.jasperreports.extension.functions.math=net.sf.jasperreports.functions.standard.MathFunctions, net.sf.jasperreports.functions.standard.LogicalFunctions
net.sf.jasperreports.extension.functions.text=net.sf.jasperreports.functions.standard.TextFunctions
net.sf.jasperreports.extension.functions.report=net.sf.jasperreports.functions.standard.ReportFunctions
Funnily enough, commenting out TEXT, running it locally with gradle run, it works without problems. But packaging it and running it with java -jar it fails to find this function. And statically importing this function leads to gradle run failing as well.
What is happening and how can I fix this? I want to distribute my FatJar on a server and run it, but this problems makes it impossible for me.

apache PIG with datafu: Cannot resolve UDF's

I'm trying the quickstart from here: http://datafu.incubator.apache.org/docs/datafu/getting-started.html
I tried nearly everything, but I'm sure it must be my fault somewhere. I tried already:
exporting PIG_HOME, CLASSPATH, PIG_CLASSPATH
starting pig with -cpdatafu-pig-incubating-1.3.0.jar
registering datafu-pig-incubating-1.3.0.jar locally and in hdfs => both succesful (at least no error shown)
nothing helped
Trying this on pig:
register datafu-pig-incubating-1.3.0.jar
DEFINE Median datafu.pig.stats.StreamingMedian();
data = load '/user/hduser/numbers.txt' using PigStorage() as (val:int);
data2 = FOREACH (GROUP data ALL) GENERATE Median(data);
or directly
data2 = FOREACH (GROUP data ALL) GENERATE datafu.pig.stats.StreamingMedian(data);
I get this name-resolve error:
2016-06-04 17:22:22,734 [main] ERROR org.apache.pig.tools.grunt.Grunt
- ERROR 1070: Could not resolve datafu.pig.stats.StreamingMedian using imports: [, java.lang., org.apache.pig.builtin.,
org.apache.pig.impl.builtin.] Details at logfile:
/home/hadoop/pig_1465053680252.log
When I look into the datafu-pig-incubating-1.3.0.jar it looks OK, everything in place. I also tried some Bag functions, same error then.
I think it's kind of a noob-error which I just don't see (as I did not find particular answers for datafu in SO or google), so thanks in advance for shedding some light on this.

Pig script is proper, the only thing that could break is that while registering datafu there were some class dependencies that coudn't been met.
Try to run locally (pig -x local) and see a detailed log.
Check also the version of pig - it should be newer than 0.14.0.

Run an ABCL code that uses cl-cppre

With reference to my previous question,
Executing a lisp function from Java
I was able to call lisp code from Java using ABCL.
But the problem is, the already existing lisp code uses CL-PPCRE package.
I can not compile the code as it says 'CL-PPCRE not found'.
I have tried different approaches to add that package,
including
1) how does one compile a clisp program which uses cl-ppcre?
2)https://groups.google.com/forum/#!topic/cl-ppcre/juSfOhEDa1k
Doesnot work!
Other thing is, that executing (compile-file aima.asd) works perfectly fine although it does also require cl-pprce
(defpackage #:aima-asd
(:use :cl :asdf))
(in-package :aima-asd)
(defsystem aima
:name "aima"
:version "0.1"
:components ((:file "defpackage")
(:file "main" :depends-on ("defpackage")))
:depends-on (:cl-ppcre))
The final java code is
interpreter.eval("(load \"aima/asdf.lisp\")");
interpreter.eval("(compile-file \"aima/aima.asd\")");
interpreter.eval("(compile-file \"aima/defpackage.lisp\")");
interpreter.eval("(in-package :aima)");
interpreter.eval("(load \"aima/aima.lisp\")");
interpreter.eval("(aima-load 'all)");
The error message is
Error loading C:/Users/Administrator.NUIG-1Z7HN12/workspace/aima/probability/domains/edit-nets.lisp at line 376 (offset 16389)
#<THREAD "main" {3A188AF2}>: Debugger invoked on condition of type READER-ERROR
The package "CL-PPCRE" can't be found.
[1] AIMA(1):
Can anyone help me?

You need to load cl-ppcre before you can use it. You can do that by using (asdf:load-system :aima), provided that you put both aima and cl-ppcre into locations that your ASDF searches.

I used QuickLisp to add cl-ppcre (because nothing else worked for me).
Here is what I did
(load \"~/QuickLisp.lisp\")")
(quicklisp-quickstart:install)
(load "~/quicklisp/setup.lisp")
(ql:quickload :cl-ppcre)
First 2 lines are only a one time things. Once quickLisp is installed you can start from line 3.

Yaml fixtures of java playframework doesn't work as expected

I tried to make the zenTasks tutorial for the play-java framework (I use the current playframework, which is 2.3.2). As it comes to testing and adding fixtures I'm kind of lost!
The docu states that
Edit the conf/test-data.yml file and start to describe a User:
- !!models.User
email: bob#gmail.com
name: Bob
password: secret
...
And I should download a sample (which is in fact a dead link!)
So I tried myself adding more Users like this:
- !!models.User
email: somemail1#example.com
loginName: test1
- !!models.User
email: somemail2#example.com
loginName: test2
If I then try to load it via
Object load = Yaml.load("test-data.yml");
if (load instanceof List){
List list = (List)load;
Ebean.save(list);
} else {
Ebean.save(load);
}
I get the following Exception:
[error] Test ModelsTest.createAndRetrieveUser failed:
java.lang.IllegalArgumentException: This bean is of type [class
java.util.ArrayList] is not enhanced?, took 6.505 sec [error] at
com.avaje.ebeaninternal.server.persist.DefaultPersister.saveRecurse(DefaultPersister.java:270)
[error] at
com.avaje.ebeaninternal.server.persist.DefaultPersister.save(DefaultPersister.java:244)

[error] at com.avaje.ebean.Ebean.save(Ebean.java:453) [error]
at ModelsTest.createAndRetrieveUser(ModelsTest.java:18) [error]
...
How Am I supposed to load more than one User (or whatever object I wish) and parse them without exception?

In Ebean class save method is overloaded.
save(Object) - expects parameter which is entity (extends Model, has #Entity annotation)
save(Collection) - expects collection of entities.
Yaml.load function returns objecs which can be:
Entity
List of entities
But if we simply do:
Object load = Yaml.load("test-data.yml");
Ebean.save(load);
then save(Object) method will be called. This is because at compile time compiler doesn't know what exactly will Yaml.load return. So above code will throw exception posted is question when there is more then one user in "test-data.yml" file.
But when we cast the result to List as in code provided by OP then everything works good. save(Collection) method is called and all entities are saved correctly. So the code from question is correct.

I have same problem with loading data from "test-data.yml". But I have found solution for this problem. Here is http://kewool.com/2013/07/bugs-in-play-framework-version-2-1-1-tutorial-fixtures/ solution code. But all Ebean.save methods must be replaced with Ebean.saveAll methods.

AST eclipse, adding arguments to a MethodInvocation

Im trying to add arguments to the arguments list of a MethodInvocation and it doesnt seem to work, I can remove objects but I cant see to add them.
My end goal is to take 2 MethodInvocation that invoke the same method with different arguments and convert it to 1 MethodInvocation that has a ConditionalExpression as an argument.
Example:
if (A){
System.out.println("hi");
} else {
System.out.println("hey");
}
Will be converted to:
System.out.println((A ? "hi" : "hey"));
So I would also appreciate it if someone knwos how to convert the argument list to 1 big Expression I can place in the ConditionalExpression.
Thanks!
EDIT: sorry forgot to mention is it a code formatting plug-in for ecplise
EDIT2: the code I am trying to run:
final ExpressionStatement thenStmnt=(ExpressionStatement)((Block)node.getThenStatement()).statements().get(0),
elseStmnt=(ExpressionStatement)((Block)node.getElseStatement()).statements().get(0);
MethodInvocation thenMethod=(MethodInvocation)thenStmnt.getExpression(),
elseMethod=(MethodInvocation)elseStmnt.getExpression();
final MethodInvocation method=ast.newMethodInvocation();
method.setName(ast.newSimpleName("add"));
method.arguments().add(0, elseMethod.arguments().get(0));
ast is a given leagal AST and node is a given leagal IfStatement.

Solved, problem was here:
method.arguments().add(0, elseMethod.arguments().get(0));
If you want to take or copy something that is already part of your original code, meaning already exist in the AST you have to use r.createCopyTarget, like so:
method.arguments().add(0, r.createCopyTarget(elseMethod.arguments().get(0)));
