无法创建 .jar 文件。 使用 gradle 时出错，尤其是 ./gradlew build。 获取 java.lang.IllegalAccessError

Question

I was trying to build a jar file. Basically trying to dockerize my project. But I was unable to create a jar file. I was getting error. While I was running ./gradlew build I was getting the error:

l (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.code to unnamed module @0x7fd2416f

So, I ran gradle --stacktrace , then the following reason of error showed up:

e=log4j-api, version=2.14.1}] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

build.gradle

plugins {
    id 'org.springframework.boot' version '2.5.2'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'org.projects'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '15'
def versionLog4j = '2.14.1'
def versionLombok = '1.18.20'
repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: versionLog4j
    compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: versionLog4j
    compile group: 'org.projectlombok', name: 'lombok', version: versionLombok
    annotationProcessor group: 'org.projectlombok', name: 'lombok', version: versionLombok
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    runtimeOnly 'org.postgresql:postgresql'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

Additionally, I have a warning which I can not fix: Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.

Answer 1

您能否使用命令行参数运行 Gradle 构建 --warning-mode=all 以查看您的构建中究竟使用了哪些已弃用的功能？

Answer 2

Instead of

dependencies {
    compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: versionLog4j
    compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: versionLog4j
}

use:

dependencies {
    implementation group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.14.1'
    implementation group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.14.1'
}
