【问题描述】：

我正在尝试运行在 here 上共享的非常基本的应用程序

我能够让构建运行，但最终失败并出现以下错误：

    [creator]     Paketo BellSoft Liberica Buildpack 9.0.1
    [creator]       unable to find dependency
    [creator]       no valid dependencies for native-image-svm, 8.*, and io.paketo.stacks.tiny in [(jdk, 8.0.312, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *]) (jre, 8.0.312, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *]) (jdk, 11.0.13, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *]) (jre, 11.0.13, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *]) (native-image-svm, 11.0.13, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *]) (jdk, 17.0.1, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *]) (jre, 17.0.1, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *]) (native-image-svm, 17.0.1, [io.buildpacks.stacks.bionic io.paketo.stacks.tiny *])]
    [creator]     ERROR: failed to build: exit status 1

这是我的 build.gradle ：

plugins {
        id 'org.springframework.boot' version '2.6.2'
        id 'io.spring.dependency-management' version '1.0.11.RELEASE'
        id 'java'
        id 'org.springframework.experimental.aot' version '0.11.1'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'


repositories {
        mavenCentral()
        maven { url 'https://repo.spring.io/release' }

}

dependencies {
        implementation 'org.springframework.boot:spring-boot-starter-web'
        testImplementation('org.springframework.boot:spring-boot-starter-test')
}

test {
        useJUnitPlatform()
}

bootBuildImage {
    builder = "paketobuildpacks/builder:tiny"
    environment = [
        "BP_NATIVE_IMAGE" : "true"
    ]
    buildpacks = ["gcr.io/paketo-buildpacks/java-native-image:7.1.0"]
}

如果能帮助我解决这个问题，我将不胜感激。

【解决方案1】：

所以我设法解决了它。源代码兼容性设置为 1.8，可能 Java 8 与 paketo buildback 不兼容。

将 build.gradle 中的 sourceCompatibility 升级到 11 或 17 可解决此问题：

sourceCompatibility = '11'

// or

sourceCompatibility = '17'
