RuntimeException：Sikulix致命错误：loadlib：opencv_java342.dll不在任何libs文件夹中

Question

Project structure (full project can be downloaded here ):

Launcher.java class:

import org.sikuli.script.Pattern;

public class Launcher {
    public static void main(String[] args)
    {
        Pattern p1 = new Pattern(Launcher.class.getResource("sample.png"));
    }
}

build.gradle file:

plugins {
    id 'java'
}

group 'com.myproj'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
    maven {
        url "http://oss.sonatype.org/content/groups/public"
    }
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile group: 'com.sikulix', name: 'sikulixapi', version: '1.1.4-SNAPSHOT'
}

Program throws following runtime error:

loadlib: opencv_java342.dll not in any libs folder

Interesting thing is that my code worked in the morning smoothly. And when I got back home in the evening something went wrong. Can't run it anymore.. Thank you for any help!

What I've tried:

• reload sikulixapi package using Gradle from scratch
• download 3.4.2 opencv and load it in runtime like suggested here
• add opencv_java342.dll directly to the project as described here
• even tried to launch the project on different Windows machine to exclude environment issues - still fails

Answer 1

It happened, that there was a bug in the latest snapshot. Full conversation with developers can be found here .

So, in this situation you have at least two options:

1. Wait until developers fix the issue and introduce new snapshot. Bugs/questions can be reported here .

2. Tell gradle/maven to use previous stable version of sikulixapi library. Full list of currently available snapshots can be found here . Gradle example:

     dependencies { compile group: 'com.sikulix', name: 'sikulixapi', version: '1.1.4-20181214.081346-62' }
