[2.0.6]sikulixapi usage in Gradle projects

You have to understand the Homebrew concept for macOS M1 machines (see Home-brew docs).

In 2.0.6 (only snapshots available at the moment) I try to reflect all specific aspects of macOS M1 with respect to SikuliX

The snippets from 2.0.6 are only to give you some insights about what you would have to do in your wrapper.
Setting the jna-path correctly is the key feature.

     if (Commons.runningMac()) {
        String libPath = "/usr/local/lib";
        if (Commons.runningMacM1()) {
          libPath = "/opt/homebrew/lib";
        }
        File libTess = new File(libPath, "libtesseract.dylib");
        if (libTess.exists()) {
          Commons.jnaPathAdd(libPath); //----------------------------- add the path
        } else {
          throw new SikuliXception(String.format("OCR: validate: libtesseract.dylib not in %s", libPath));
        }
      }

// the respective method from Commons:

  public static String jnaPathAdd(String sFolder) {
    String jnaPath = System.getProperty("jna.library.path");
    if (null == jnaPath) {
      jnaPath = "";
    }
    File folder = new File(sFolder);
    if (!folder.exists()) {
      return null;
    }
    if (!jnaPath.isEmpty()) {
      jnaPath = File.pathSeparator + jnaPath;
    }
    jnaPath = folder.getAbsolutePath() + jnaPath;
    System.setProperty("jna.library.path", jnaPath);
    return jnaPath;
  }

Hi! Raiman,

Thanks for this quick reply. What I understand is that I'd better wait for 2.0.6 in order to use this machine, right?

It would be helpful if you try with the actual snapshot 2.0.6 from today.

Waiting for the final release does not change your situation:
On macOS M1 you will always need a valid Homebrew setup or a symlink for libtesseract.dylib in a folder /opt/homebrew/lib.

The actual snapshot and hence the final version needs Tesseract 5.0.1

Hi! RaiMan,

Could you please let me know where to download actual snapshot 2.0.6 and how to use it?

Thanks,
Juliana

Hi! RaiMan,

I found the 2.0.6 jar file but it is sikulixide jar file. Where can I find sikulixapi jar file so that I can run my test case written in java from eclipse?

Maven coordinates:
com.sikulix::sikulixapi::2.0.6-SNAPSHOT
from
snapshot-repo OSSRH

Hi! RaiMan,

I have a Gradle java project and in build.gradle file I put the following line
api "com.sikulix.sikulixapi:2.0.6-SNAPSHOT:2.0.6"
I got the following issue:
Could not resolve: com.sikulix.sikulixapi:2.0.6-SNAPSHOT:2.0.6

If I put
api "com.sikulix:sikulixapi:2.0.6-SNAPSHOT"
I got following issue:
Could not resolve: com.sikulix:sikulixapi:2.0.6-SNAPSHOT

I don't know how to make it work in my Gradle java project. Could you please help?

Sorry, no Gradle experience.

Correct should be:
com.sikulix:sikulixapi:2.0.6-SNAPSHOT

But I guess (as with Maven) you have to tell Gradle about the snapshot repository on OSSRH:

 <repositories>
    <repository>
      <id>OSSRH</id>
      <snapshots></snapshots>
      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
    </repository>
  </repositories>

This is for Maven, but there surely is a similar option with Gradle.

Hi! RaiMan,

I just tried this yesterday and made it work with following build.gradle configuration. Both options are working fine: Sikuli can find images and do the click.
Option1:
*************************************
repositories {
 maven {
  url = 'https://oss.sonatype.org/content/repositories/snapshots'
 }
}
dependencies {
 api(group: 'com.sikulix', name: 'sikulixapi', version: '2.0.6-SNAPSHOT')
}
*************************************

Option2:
*************************************
repositories {
 maven {
  url = 'https://oss.sonatype.org/content/repositories/snapshots'
 }
}
dependencies {
 compile "com.sikulix:sikulixapi:2.0.6-SNAPSHOT"
}
*************************************

But I encountered a new issue: when I tried to recognize text from an image using the following code:
screen.find(new Pattern(imageFileName).similar((float) similarity).targetOffset(image.getOffsetX(),
          image.getOffsetY())).right(offset).text().trim()
I got the following error:
*************************************

 at org.sikuli.script.Element.text(Element.java:1155)
*************************************
I found the actual location is "/opt/homebrew/Cellar/tesseract/5.0.1/lib/libtesseract.dylib". Could you please help?

Thanks,
Juliana

--- I found the actual location is "/opt/homebrew/Cellar/tesseract/5.0.1/lib/libtesseract.dylib".
This is we're the stuff is built and made ready.
finally there are symlinks created in /opt/homebrew/lib (brew link ...). there should be a libtesseract.dylib as symlink.
See comment #1.

Hi! RaiMan,

I changed some configuration in gradle.build and installed some libraries on M1 CPU mac machine. Now I still can do the click and verify image with sikuli2.0.6-SNAPSHOT but I still cannot get text from image and I see the following error which is different than above. Do you have any idea that why I get the following error?
***********************************************************************

Just checked again on my iMac M1.

My Tesseract is on version 5.0.3 and it works.

Put a
Debug.on(3);
before the first use of any SikuliX feature and you should get logs like this when using find() and text():

[debug] OCR: Tesseract version found: 5.3.0 expected: 5.0.1 --- should work
[debug] OCR: Tess4J 5.1.1 --- Tesseract 5.3.0

Hi RaiMan, I am having issues with Sikulli on my M1 Mac as well. I have added the snapshots repo to my build.gradle file like this:

exclusiveContent {
  forRepository {

   maven {
    name = 'OSSRH-Snapshots'
    url = 'https://oss.sonatype.org/content/repositories/snapshots'
    mavenContent {
     snapshotsOnly()
    }
   }
  }
  filter {
   includeGroup 'com.sikulix'
  }
 }

api(group: 'com.sikulix', name: 'sikulixapi', version: '2.0.6-SNAPSHOT')

However, when I build the project, I am getting the following error:

  > Could not find org.openpnp:opencv:[4.7.0,].
     Searched in the following locations:
       - https://repo1.maven.org/maven2/org/openpnp/opencv/[4.7.0,]/opencv-[4.7.0,].pom
       - https://oss.sonatype.org/content/repositories/releases/org/openpnp/opencv/[4.7.0,]/opencv-[4.7.0,].pom
     Required by:
         project :TestNGFramework > com.sikulix:sikulixapi:2.0.6-SNAPSHOT:20230417.153849-20

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

Do you have an idea what might be wrong? I can see that the version of opencv looks strange "opencv-[4.7.0,]"(there is a comma in the end, which might be causing the issue). If I try to browse the repository manually, I can find https://repo1.maven.org/maven2/org/openpnp/opencv/4.7.0-0/

Thank you in advance for your help!

Anna

sikulixapi pom has this dependency with a version [4.7.0,] which in Maven means: take at least version 4.7.0, but if available any newer version .

I have no Gradle experience and do not know how to tell Gradle, what to do with such a version specification.

May be it is possible to tell Gradle to ignore it and you might add a correct dependency for org.openpnp:opencv:4.7.0 or so.
