Work Manager dependency is causing dex merger issue in android project

I have implemented a new feature in my application, and the feature requires WorkManager in my project and I added dependency:
implementation "android.arch.work:work-runtime:1.0.0-alpha12"
The feature is working fine in my sample but when I integrated that sample to actual project and getting below build error after adding above library.

I tried enabling multidex and even tried updating versions of work-runtime library but it didn't helped and I still obtained this issue.
I am stuck on this issue. Any help would be really appreciated..!!!

Always rebuild projects after changed androidTest code, when update grade to java8

Before upgrading the version of Java from 1.7 to 1.8, a bunch of test case which is running fine. But, after that, when I change any test case and run the project always failed, must be rebuild all projects.
According to the exception below, I guess that desugaring class occurs errors ,and desugaring is related with Java8.
any one have good idea?

Firstly ,I'm sorry for this question as no description.
Before we upgrading the version of Java from 1.7 to 1.8, writing androidTest code is ok. After that ,when we change any codes and run with androidTest project always failed, must be rebuild all projects.
According to the exception above, guess that desugaring class occurs errors ,and desugaring is related with Java8.

CIRCULAR REFERENCE:java.lang.NullPointerException from DexFileReader

I attempted to upgrade my build environment to Gradle 4.4 today, and ran into the following error while attempting build an APK:
[CIRCULAR REFERENCE:java.lang.NullPointerException]
Caused by: java.lang.NullPointerException
at com.android.tools.r8.dex.DexFileReader$AttributesAndAnnotations.<init>(DexFileReader.java:1129)

at java.util.concurrent.ForkJoinTask$AdaptedRunnableAction.exec(ForkJoinTask.java:1386)
I then attempted to build using Gradle 4.5, and am seeing the same error. This application builds fine using Gradle 4.1, but a problem I reported separately is forcing me to upgrade at a time when I can't afford to chase down mysterious Dex errors.
Note: I disabled Proguard, but that had no effect.
In order to perform the Gradle upgrade, all I did was change the version in my gradle-wrapper.properties file; no other code or configuration changes were made.
Here is the full, very long stack trace, from the Gradle console, along with a few console lines -- which indicate that Gradle is attempting to complete the transformDexArchiveWithDexMerger task when this NullPointerException is thrown.
Removed unused resources: Binary resource data reduced from 6200KB to 6191KB: Removed 0%

It turned out that this was due to our use of the 9.0.0-SNAPSHOT version of the Butterknife plugin.
When we switched from this:
classpath 'com.jakewharton:butterknife-gradle-plugin:9.0.0-SNAPSHOT'
... to an older version that builds for us:
classpath 'com.jakewharton:butterknife-gradle-plugin:8.5.1'
... the CIRCULAR REFERENCE NullPointerException Dex error went away.
Moral of the story: stick with stable, specific versions of your Gradle plugins.

Add following dependency in your app gradle file
mention multiDexEnabled true in default config of your app gradle.
compile 'com.android.support:multidex:1.0.3'
after that
extend your application class by MultiDexApplication
and then keep you old code as it is in your application class
and also mention below following terms in your app gradle file.
android {
dexOptions {
preDexLibraries = false
javaMaxHeapSize "4g"
}
}
You can check also from below link
DexGuard java.io.IOException: The same input jar
May be this will work for you...

I think that's because of com.google.code.findbugs poackage. I've tried to force dependencies, but it didn't work
configurations.all {
resolutionStrategy {
preferProjectModules()
resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.1'
resolutionStrategy.force 'com.google.code.findbugs:annotations:3.0.1'
}
}
I successfully built project when I added
configurations {
compile.exclude group: "com.google.code.findbugs"
}
However, I don't wanna totally exclude findbugs.
Yes, I've been executing gradle clean, removing .gradle folder and invalidating caches in Android Studio.
Do you have any idea how to solve this problem?
[EDIT]
Yes, I have enabled multidex and gradle built my project on Android Studio 2.3.4
