尝试模块化Gradle SpringBoot项目，但在尝试构建时出现“错误：找不到符号”？

我有一个正在工作的单模块Java项目，我试图将其分解为两个模块：一个库和一个应用程序模块。我从顶层build.gradle中提取了Java库，并将它们填充到库build.gradle中，并将SpringBoot / Docker / MySQL相关的依赖项保留在应用程序构建文件中。运行./gradlew构建会由于应用程序中的龙目岛内容上出现“找不到符号”错误而导致错误。

我添加了顶层settings.gradle（下面的代码），提取了所有Java库并放入library / build.gradle（下面的代码），并在application / build.gradle中添加了对库的引用（下面的代码） 。

settings.gradle：

rootProject.name = 'order-routing'
include 'library'
include 'application'

库/ build.gradle：

buildscript {
    repositories { mavenCentral() }
}

plugins {
    id "io.spring.dependency-management" version "1.0.5.RELEASE"
}

apply plugin: 'project-report'
apply plugin: 'java'

ext { springBootVersion = '2.1.6.RELEASE' }

jar {
    baseName = 'order-routing-library'
    version = '0.0.1-SNAPSHOT'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compileOnly 'org.projectlombok:lombok'
    testCompileOnly 'org.projectlombok:lombok'
    compileOnly 'com.google.code.gson:gson:2.8.5'
    runtimeOnly 'com.h2database:h2:1.4.197'
    compile 'mysql:mysql-connector-java'
    annotationProcessor 'org.projectlombok:lombok'
    testAnnotationProcessor 'org.projectlombok:lombok'
    compile('org.springframework.boot:spring-boot-starter')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile 'org.springframework.boot:spring-boot-starter-web'
    compile 'com.google.cloud.sql:mysql-socket-factory-connector-j-8:1.0.14'
}

和application / build.gradle（注意，我添加了“ compile project（'：library'）”）：

buildscript {
    ext { springBootVersion = '2.1.6.RELEASE' }
    repositories { mavenCentral() }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath('se.transmode.gradle:gradle-docker:1.2')
    }
}

plugins {
    id "io.spring.dependency-management" version "1.0.5.RELEASE"
    id 'org.springframework.boot' version '2.1.6.RELEASE'
    id 'java'
    id "org.flywaydb.flyway" version "5.2.4"
}

apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'project-report'
apply plugin: "maven"
apply plugin: 'docker'
repositories {
    mavenCentral()
}

dependencies {
    compile 'mysql:mysql-connector-java'
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile project(':library')
}

sourceCompatibility = 8
targetCompatibility = 8

compileJava.options.compilerArgs.add '-parameters'
compileTestJava.options.compilerArgs.add '-parameters'

configurations {
    all*.exclude group: "org.hibernate", module: "hibernate-entitymanager"
    all*.exclude group: "org.apache.tomcat", module: "tomcat-jdbc"
}

flyway {
    url = 'jdbc:mysql://localhost/ordb'
    user = 'flyway'
    table = 'schema_version'
}

bootJar {
    baseName = 'order-routing-application'
    version = '0.0.1-SNAPSHOT'
    mainClassName = 'com.pokemonmerch.orderrouting.OrderRoutingApplication'
}

预期结果：运行'./gradlew build'并看到成功的构建。实际：在一堆lombok生成的方法上出现“错误：找不到符号”
