Gradle发布版本目录至Nexus报错：NoSuchAlgorithmException

执行gradlew publish命令发布Gradle版本目录到Nexus仓库时，抛出java.security.NoSuchAlgorithmException错误，无法完成发布。但将仓库改为mavenLocal()时，版本目录可正常发布至本地Maven仓库。

另外，配置完全一致的自定义Gradle插件能成功发布到同一Nexus仓库，添加堆栈跟踪后发现错误由SSLContext.getDefault()抛出。

版本目录发布脚本（原错误脚本） #

buildscript {
    dependencies {
        classpath("com.android.tools.build:gradle:7.2.0")
    }

}
plugins {
    id ("version-catalog")
    id ("maven-publish")
}
catalog {
    versionCatalog {
        from(files("gradle/libs.versions.toml"))
    }
}

publishing {
    publications {
        create<MavenPublication>("VersionCatalog") {
            groupId = "com.phinneyridge"
            artifactId = "com.phinneyridge.version.catalog"
            version = "1.0.0"
            from(components["versionCatalog"])
        }
        repositories {
            maven {
                name = "PhinneyRidgeRepository"
                url = uri(System.getenv()["PhinneyRidgeReleaseRepoUrl"].toString())
                credentials {
                    username = System.getenv().get("PhinneyRidgeRepoUser").toString()
                    password = System.getenv().get("PhinneyRidgeRepoUserPW").toString()
                }
                println(url)
                println(credentials.username + ":" + credentials.password)
            }
        }
    }
}

原因分析 #

• 版本目录发布脚本中，repositories块被错误嵌套在publications内部，Gradle处理时会出现配置上下文异常，当连接HTTPS的Nexus仓库时，异常会触发SSL上下文初始化失败，进而抛出NoSuchAlgorithmException。
• 本地Maven仓库不需要SSL加密连接，所以错误配置不会暴露；而插件脚本的repositories是正确放在publishing根级别下，与publications同级，因此能正常发布。

解决办法 #

修改版本目录发布脚本，将repositories块从publications内部移出，放在publishing根级别，与publications同级：

修改后的版本目录发布脚本 #

buildscript {
    dependencies {
        classpath("com.android.tools.build:gradle:7.2.0")
    }

}
plugins {
    id ("version-catalog")
    id ("maven-publish")
}
catalog {
    versionCatalog {
        from(files("gradle/libs.versions.toml"))
    }
}

publishing {
    publications {
        create<MavenPublication>("VersionCatalog") {
            groupId = "com.phinneyridge"
            artifactId = "com.phinneyridge.version.catalog"
            version = "1.0.0"
            from(components["versionCatalog"])
        }
    }
    // 将repositories移到publications外部，与publications同级
    repositories {
        maven {
            name = "PhinneyRidgeRepository"
            url = uri(System.getenv()["PhinneyRidgeReleaseRepoUrl"].toString())
            credentials {
                username = System.getenv().get("PhinneyRidgeRepoUser").toString()
                password = System.getenv().get("PhinneyRidgeRepoUserPW").toString()
            }
            println(url)
            println(credentials.username + ":" + credentials.password)
        }
    }
}

修改后重新执行gradlew publish命令即可正常发布版本目录到Nexus仓库。
