使用 Gradle 编译 Ceylon 示例时出错

Question

Ceylon 1.3.1 刚刚发布，新项目之一是更好地与Java projects/libraries 集成。决定试一试其中一个样本 (https://github.com/DiegoCoronel/ceylon-spring-boot) alongside the ceylon-gradle plugin (https://github.com/renatoathaydes/ceylon-gradle-plugin)。

据我所知，将这个项目变成一个多项目 Gradle 构建就是添加两个具有以下配置的文件。

settings.gradle

include 'gateway'
include 'discovery'
include 'foo'
include 'bar'
include 'foobar'

build.gradle

plugins {
    id 'com.athaydes.ceylon' version '1.3.0' apply false
}

subprojects { subprj ->
    subprj.apply plugin: 'com.athaydes.ceylon'

    repositories {
        mavenCentral()
    }

    ceylon {
        module = subprj.name
    }
}

不幸的是，构建任何模块都会导致错误，例如

$ gradle :gateway:compileCeylon

:gateway:resolveCeylonDependencies
:gateway:createDependenciesPoms
:gateway:createMavenRepo
:gateway:generateOverridesFile
:gateway:createModuleDescriptors
:gateway:importJars
:gateway:compileCeylon
source/gateway/module.ceylon:3: error: Pre-resolving of module failed: Could not find module: antlr/2.7.7
        import ceylon.interop.java "1.3.0";
        ^
ceylon compile: There was 1 error
:gateway:compileCeylon FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':gateway:compileCeylon'.
> Ceylon process exited with code 1. See output for details.

这发生在使用 Gradle 3.2

OS:           Mac OS X 10.10.5 x86_64

尝试按照插件文档中的说明在 ceylon 配置上设置其他属性，例如

ceylon {
    flatClasspath = false
    importJars = true
    forceImports = true
}

但是错误仍然存在。任何关于我可能遗漏的指示都将不胜感激。

Answer 1

这是因为 ceylon gradle 插件 does not support yet 新功能 --fully-export-maven-dependencies ...我现在创建了这个问题 ;)，所以为了让你的项目工作可能需要使用以下选项更改 each subproject/.ceylon/config：

[compiler]
source=source
resource=resource

[defaults]
encoding=UTF-8
overrides=build/overrides.xml
flatclasspath=true
fullyexportmavendependencies=false

它将禁用新的 Ceylon 功能并使用 Ceylon gradle 插件功能和生成的 overrides.xml 文件
