如何从源代码构建 kotlin-stdlib/kotlin-reflect

Question

我需要从源代码构建 kotlin-stdlib/kotlin-reflect （版本 1.9.22）。 我已将 JAVA_HOME 设置为 Java 17 并使用了

./gradlew build

。 但出现错误：

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':kotlin-stdlib:compileMainJdk7KotlinJvm'.
> Unable to download toolchain matching the requirements ({languageVersion=7, vendor=any, implementation=vendor-specific}) from 'https://api.foojay.io/disco/v3.0/ids/45dfb704e8dcceab434285501d74cd33/redirect'.

/home/xxx/.gradle/jdks/zing20

不存在。 我已下载并解压

zing20.09.1.0-1-jdk7.0.272-linux_x64.tar.gz

并再次运行。出现这个错误

FAILURE: Build failed with an exception.

     Error output:

有没有办法在没有 zing20 的情况下构建 kotlin-stdlib/kotlin-reflect ？

谢谢

此问题是缺少 Java 7 的问题。要解决此问题，有两种可能性：

1. 将 Java 7 添加到

   $HOME/.m2/toolchains.xml

2. 添加到

   local.properties

   （在

   kotlin

   项目的根目录中）属性

   kotlin.build.isObsoleteJdkOverrideEnabled=true

   - Java 8将用于编译Java 7相关类
