Google Guava PatternCompiler Issue

[ebitogu]

Hello, thanks for taking the time to port this library to Java.

I am currently integrating this library into my JavaFX Application.

I am done with the project and I need to package the Application but I keep getting

error: PatternCompiler is not public in com.google.common.base; cannot be accessed from outside package uses com.google.common.base.PatternCompiler;

I am trying to Package the app using JLink.

I can't package the application because of the above error.

Please, can you help?

You need provide more information. To my knowledge PatternCompiler is not used by LevelDb. Guava used by LevelDb is shaded to a distinct package: "com.google.thirdparty".
What is your JDK version? Stacktrace?...

@pcmind Thanks for taking the time to respond. I truly appreciate.

I have very little experience with Gradle though.However, I am building the application using JavaFX and (Gradle to fetch my dependencies).

Here is a setup of my build.gradle file

plugins {
    id 'java'
    id 'application'
    id 'org.openjfx.javafxplugin' version '0.0.7'
    id 'org.beryx.jlink' version '2.14.0'
}

group 'com.databox'
version '1'

mainClassName = "com.databox.launcher.ApplicationLoader"
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testImplementation group: 'junit', name: 'junit', version: '4.12'
    implementation group: 'org.iq80.leveldb', name: 'leveldb', version: '0.12'
    implementation group: 'org.json', name: 'json', version: '20180813'
}

javafx {
    version = "12.0.1"
    modules = ['javafx.base', 'javafx.fxml', 'javafx.controls', 'javafx.web']
}

jlink {
    options = ['--strip-debug', '--compress', '2', '--no-header-files', '--no-man-pages']
    launcher{
        name = 'DataBox'
        jvmArgs = ['-Dlog4j.configurationFile=./log4j2.xml']
    }
}

Now I am done with the application and need to package it as an executable file for the Windows platform. To do that I did gradlew jlink but I keep getting

 >Task :createMergedModule
C:\user_home\DataBox\build\jlinkbase\tmpjars\com.databox.merged.module\module-info.java:27: error: PatternCompiler is not public in com.google.commo
n.base; cannot be accessed from outside package
    uses com.google.common.base.PatternCompiler;
                               ^
1 error

> Task :createMergedModule FAILED

FAILURE: Build failed with an Exception

However, I am not using anything related to Guava.

Thanks once again.

Your failure has nothing to do with leveldb.
You need to fix your project package usage/modue-info.java.
