What I have tried, removing ant-javax.jar
downgrade junit 4.11
and exluded hamcrest from cucumber junit library and junit library

Still there is some place where this dependency for mockito core exist.
I don't know how to remove this dependency.
I am pasting some section of my gradle file for you guys to see.

testCompile (
        'net.sourceforge.pmd:pmd:5.1.1',
        'org.apache.lucene:lucene-expressions:4.10.4',
        'info.cukes:cucumber-java:1.2.4',
        'info.cukes:cucumber-picocontainer:1.2.4'

)
testCompile ('junit:junit:4.11') {
    exclude group: 'org.hamcrest'
}

testCompile ('info.cukes:cucumber-junit:1.2.4') {
    exclude group: 'org.hamcrest'
}

buildscript {
  dependencies {
    classpath (
            'com.github.jengelman.gradle.plugins:shadow:1.2.3',
            'org.apache.ant:ant:1.9.2',
            'org.ow2.asm:asm-all:5.0.2',

            'org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:1.2'
    )
 }
}

Please help!

Where is the dependency on elasticsearch? Can't see it.

Hi, Finally found 1 dependency that was causing it. dropwizard test.
Adding the dependency again:

compile fileTree (dir: 'libs')
compile (
        'io.dropwizard:dropwizard-core:0.9.1',
        'io.dropwizard:dropwizard-client:0.9.1',
        'io.dropwizard:dropwizard-assets:0.9.1',
        'org.apache.commons:commons-lang3:3.4',
        'org.apache.commons:commons-jexl:2.1.1',
        'commons-io:commons-io:2.2',
        'commons-collections:commons-collections:3.2.1',
        'com.wordnik:swagger-core_2.10:1.3.0',
        'com.fasterxml.jackson.module:jackson-module-afterburner:2.1.5',
        'com.tesco.productservice:RSCouchBase:5.3.2',

        'org.apache.logging.log4j:log4j-api:2.9.1',
        'org.apache.logging.log4j:log4j-core:2.9.1'


)

testCompile (
        'net.sourceforge.pmd:pmd:5.1.1',
        'org.apache.lucene:lucene-expressions:4.10.4',
        'info.cukes:cucumber-java:1.2.4',
        'org.elasticsearch.test:framework:6.1.1',
        'org.elasticsearch.client:transport:6.1.1',
        'info.cukes:cucumber-picocontainer:1.2.4'

)
testCompile ('junit:junit:4.11') {
    exclude group: 'org.hamcrest'
}

testCompile ('info.cukes:cucumber-junit:1.2.4') {
    exclude group: 'org.hamcrest'
}

I am getting this error now:

I'd try to exclude mockito core.

I have solved this, but now I am getting this error

I have tried this in my gradle file

test {
    exclude '**/functional/**'
    systemProperties 'environment': System.getProperty("environment")
    jvmArgs '-noverify'
    jvmArgs '-ea'
    //include '**/**'

    jacoco {
        excludes = ignoreJacoco
        append = false
        destinationFile = file("$buildDir/jacoco/jacocoTest.exec")
        classDumpFile = file("$buildDir/jacoco/classpathdumps")
    }
}

Are you trying to start elasticsearch from the JVM or something?

7

This is the gradle task to run tests
For that I thought of specifying

jvmArgs '-ea'

How to run test in intellij so that they dont give the error.
I have also tried adding -ea in VM Options of Junit in Run->Edit Configurations. Still the same error.

PS: pardon me, I also don't understand the repository fully as I am new to it and had been assigned to do some work on it.

8

-ea on VM Options, it worked.
Is there any way to do it for all tests by default?

9

You mean? In IntelliJ?

There is this documentation: https://github.com/elastic/elasticsearch/blob/master/CONTRIBUTING.md#contributing-to-the-elasticsearch-codebase

That's solved. Thanks.

I am having more trouble to create an instance of elasticsearch for testing purpose.
I am following your guide in below link:

I m having following error:

Do I need to start Elasticsearch from Terminal? I want to start test elasticsearch instance from java code for my tests.

I want to start test elasticsearch instance from java code for my tests.

It's not supported. See Elasticsearch, the server | Elastic Blog
