Whats the syntax of making a string value generic inside something.execute(String[],String) with groovy inside build.gradle file?

Below is the command cmd that is going to get executed and is working fine.
def process = cmd.execute(['PATH=D:/Project/Node_Project/build/nodejs/node-v10.10.0-win-x64'],null)
"D:/Project/Node_Project" is my project root folder.
I am trying something like below to make the path generic but it didn't work. ${project.buildDir} also didn't work.
def process = cmd.execute(['PATH=${project.projectDir}/build/nodejs/node-v10.10.0-win-x64'],null)
I want to know what is the correct format to make it generic.
https://docs.groovy-lang.org/latest/html/groovy-jdk/java/lang/String.html#execute(java.lang.String[],%20java.io.File)
The above link contains the documentation for the syntax only but no examples to solve my problem.

How am I supposed to extract properties from a node in Apache Jackrabbit from xml?

I have been playing around with the example number three in here http://jackrabbit.apache.org/jcr/first-hops.html , however to me it remains unclear how to get access to the properties of a node.
In the first screenshot
I used the debugger from my IDE and I evaluated this expression
session.getNode("/importxml/xhtml:html/xhtml:body/mathml:math/mathml:apply/mathml:apply[2]/mathml:apply[2]/mathml:cn").getProperty("jcr:xmltext/jcr:xmlcharacters").getString().trim();
You can see how I can get access to "jcr:xmltest/jcr:xmlcharacters" and have 2 as a result.
However, when I try to get this information, get this property out of the node, I am unable to perform this operation as in this screenshot.
This is the code fragment in the above screenshot:
var node = session.getNode("/importxml/xhtml:html/xhtml:body/mathml:math/mathml:apply/mathml:apply[2]/mathml:apply[2]/mathml:cn");
var properties = node.getProperties();
List<string> result = new ArrayList<>();
while(properties.hasNext()) {
Property property = properties.nextProperty();
result.add(property.getString().trim());
}
return result;
You can see how I get as a response only a value containing "nt:unstructured".
Unfortunately I couldn't find many code examples online, on Github, etc. many outdated, and also, there are not books as there are for Scrapy or other libraries/frameworks.
Thank you in advance.
Have a nice day!

In the first case, you are looking at the properties of:
/importxml/xhtml:html/xhtml:body/mathml:math/mathml:apply/mathml:apply[2]/mathml:apply[2]/mathml:cn/jcr:xmltext
In the second case:
/importxml/xhtml:html/xhtml:body/mathml:math/mathml:apply/mathml:apply[2]/mathml:apply[2]/mathml:cn
Note the different paths.

Can't get the routes object in play framework to show my custom route

I'm attempting to do a reverse lookup on a route I've created.
The route is defined as such in my routes file:
POST /login controllers.Web.Application.authenticate
However, when I try to do a reverse on it in a form I made, I can't seem to find it. I'm attempting to do a reverse like this:
#helper.form(action = routes.login())) {
rest of the form here...
}
However, the login appears in red in intellij and when attempting to run the program, I get the following error:
play.sbt.PlayExceptions$CompilationException: Compilation error[value login is not a member of object controllers.routes]
I've attempted recompiling the project multiple times and looking around the docs, but it's just not working... Any ideas?

So, an interesting thing happened recently and I found a way to point to the original structure properly. To do so, rather than writing:
routes.Web.Application.authenticate()
As Tyler suggested, I was supposed to write:
Web.routes.Application.authenticate()
Which is totally counter-intuitive and all, but that allows me to use the original package structure.

Edit:
As we discovered in the comments, the reverse router doesn't seem to like sub packages. You should remove the Web part of your package, and move everything up a level, then change the code to be this:
#helper.form(action = routes.Application.authenticate())) {
rest of the form here...
}
Original answer:
You need to refer to the controller function, and not the name of the route, so it should look something like this:
#helper.form(action = routes.Web.Application.authenticate())) {
rest of the form here...
}

Gradle CopySpec: list contents

In order to avoid duplication, I want to use several CopySpecs both for creating an EAR file and for creating the "Classpath:" entry in the manifest of one of the WARs. I wanted to simply read the contents of the CopySpecs for that, but I could not find any obvious way to do that, even after reading the code. Is this even possible from a build script? Is there a better way to achieve the same result?

Instead of a CopySpec, I used a fileTree:
def myFiles = fileTree('/files').matching {
include 'my*.jar'
}
So far, this seems to work fine for both purposes:
// ear
into('/') {
from myFiles
}
// classpath
files(configurations.deploy, configurations.earlib, myFiles)

How does Java generate signatures for Methods?

I have an Java class with a static final method getAll:
public static final Vector<Category> getAll(Context context, ContentValues where) {
ArrayList<Integer> IDs = null;
if(where != null && where.containsKey(DatabaseAdapter.KEY_PRODUCT)) {
IDs = OvertureItem.getAll(context, DatabaseAdapter.TABLE_PRODUCT_CATEGORY, new String[] { DatabaseAdapter.KEY_CATEGORY }, where);
} else {
IDs = OvertureItem.getAll(context, DatabaseAdapter.TABLE_CATEGORIES, where);
}
Vector<Category> categories = new Vector<Category>();
for(Integer id: IDs) {
categories.add(Category.get(context, id));
}
return categories;
}
Now I want to hand in null as a value for the where statemant so that it will just be ignored later on in the code. Anyway in the testcase for this method I have:
Vector<Category> categories = Category.getAll(context, null);
Which then in turn gives me a NoSuchMethodError. I don't know exactly why it does that. The only thing I could imagine is that the null I hand in would not match the signature of the above method. But how can I overcome this? I already thought of overloading. But this would just end in rewriting most of the code. At least when I do it, how I think.
Any suggestions on that?
Phil
P.S. This is the stack trace I get:
java.lang.NoSuchMethodError: com.sap.catalogue.model.Category.getAll
at com.sap.overture.test.model.CategoryTest.testGetAll(CategoryTest.java:59)
at java.lang.reflect.Method.invokeNative(Native Method)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:169)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:154)
at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:430)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1447)

If the method did not exist at compile-time, then the code would not compile.
If you get NoSuchMethodError at run-time, then this suggests that the version of the Category class you are running against is different than the version of the Category class you are compiling against.
What is your setup like - is this class in the same project? Are you copying in JARs from another project?

The real answer
So I now finally figured it out and it wasn't as obvious as I expected. I started wondering, when every new test case for any new method I wrote would give me the NoSuchMethodError. So I digged a little bit deeper and then, suddenly it came to my mind: "I changed the package name of the android application". I thought this would not make any difference to the test project as long as I kept the properties right in the AndroidManifest.xml but I was wrong!
In fact when your application package is named com.foo.bar.app, the package for your tests has to be named com.foo.bar.app.test! What happened was, that with my old configuration somehow the classes that sat in the bin/ folder were used. I thought, that they should have been deleted when I cleaned the project but they weren't. This way all of the older test cases would still pass and only the new ones would give me the NoSuchMethodError. After I deleted the bin/ folder manually I got a whole bunch of errors. I then renamed the package holding the test cases and did a full clean/ rebuild on the project et voilá everything is back to normal again.
Thanks for all the tips! I really appreciate your help that just kept me digging to the bottom of the problem. Hope this here will help anybody with the same problem in the future.
