Error after upgrading gradle

After upgrading my gradle, I got this errors which I don’t know how to fix.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDebugResources'.

This is my project level build.gradle.

/    / Top-level build file where you can add configuration options common to all sub-projects/modules.
    buildscript {
        repositories {
            jcenter()
            google()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.2.0'
        }
    }

    allprojects {
        repositories {
            jcenter()
            google()
            maven { url 'https://maven.google.com/' }
        }
    }

This is my gradle-wrapper.properties.

This is my app level build.gradle.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '25.0.0'

    defaultConfig {
        applicationId "com.csipsimple"
        minSdkVersion 14
        targetSdkVersion 23
    }
    useLibrary 'org.apache.http.legacy'

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:23.1.0'
    compile project(':sherlok')
    configurations.compile.exclude module: 'support-v4'
}

The app contains a project app module named sherlok.

After making some changes, now I’m getting this errors.
