在gradle项目中使用platform导入其他gradle公共库项目时报错
在别的项目中使用platform导入内部公共库时报错, 报错信息如下:

公共库项目应该使用org.gradle.java-platform插件而不是java, 这样才能使用platform导入
解决方案
- 增加插件
plugin("org.gradle.java-platform")- 允许该platform项目可以导入其他platform作为依赖
configure<JavaPlatformExtension> {
allowDependencies()
}- 发布到Maven仓库的配置要注意平台和library的区别
when (!isPlatform()) {
true -> {
from(components["java"])
versionMapping {
usage("java-api") {
fromResolutionResult()
}
usage("java-runtime") {
fromResolutionResult()
}
}
}
else -> from(components["javaPlatform"])
}
