问题描述
在我的gradle依赖关系中，我希望能够使用'default'版本并自动映射到特定版本的库。
作为例如我可能在我的build.gradle中有以下内容：
依赖项{
compile（group：'org.hibernate '，'hibernate-core'，'default'）
code 解决方案我希望这给我相当于
pre code> dependencies {
compile（group：'org.hibernate'，模块：'hibernate-core'，版本'4.3.0.Beta4'）
}
映射在一个文件中指定，该文件包含类似于
org.hibernate.hibernate-core = 4.3之类的键/值对.0 .Beta4
它被读入名为versionMap的项目中的HashMap类型的扩展属性。 / p>
我可以让这个映射与fo相当愉快地工作放在我的build.gradle文件中
配置{
全部{
resolutionStrategy {
eachDependency {DependencyResolveDetails详细信息 - >
if（details.requested.getVersion（）==default）{
def key = details.requested.getGroup（）+。 details.useVersion（versionMap.get（key））
}
}
}
}
$ / code> （我需要承认Peter Niederwieser帮助我达到这个目标）
由于我在许多项目中需要同样的东西，所以我想创建一个插件，所以我创建了一个插件项目，并且它的构建都很好，但是当我尝试并运行它我无法访问resolutionStrategy来设置逻辑。我的插件代码如下所示：
import org.gradle.api.Plugin;
import org.gradle.api.Project;
导入org.gradle.api.artifacts.DependencyResolveDetails;
import org.gradle.api.artifacts.ConfigurationContainer;
import org.gradle.api.artifacts.ResolutionStrategy;
class DefaultVersionsPlugin implements Plugin< Project> {
@Override
public void apply（Project project）{
def strategy =
{DependencyResolveDetails details - >
if（details.requested.getVersion（）==default）{
def key = details.requested.getGroup（）+。 details.useVersion（ext.versionMap.get（key））
}
}
ConfigurationContainer配置= project.getConfigurations（ ）;
configurations.each {config - >
printlnconfig：+ config + - + config.resolutionStrategy
config.resoultionStrategy.eachDependency {strategy}
}
}
}
上面的println给出了有效的输出，但是下面的行给出了一个错误。
config：configuration'：alerting：archives' - org.gradle.api.internal。 artifacts.ivyservice.resolutionstrategy.DefaultResolutionStrategy_Decorated@e2d0ab
失败：构建失败，出现异常。

改变
ConfigurationContainer配置= project.getConfigurations（）;
configurations.each {config - >
printlnconfig：+ config + - + config.resolutionStrategy
config.resoultionStrategy.eachDependency {strategy}
}
$ b $ p project.getConfigurations（）。all {config - >
config.resolutionStrategy.eachDependency {DependencyResolveDetails详细信息 - >
if（details.requested.getVersion（）==default）{
def key = details.requested.getGroup（）+。 + details.requested.getName（）+.version.default
details.useVersion（project.ext.versionMap.get（key））
}
}
}
并且内联移动闭包定义（不确定内联是否产生了影响）。
In my gradle dependencies I want to be able to use a version of 'default' and have that automatically map to a specific version of a library.
As an example I may have the following in my build.gradle:
dependencies {
compile (group: 'org.hibernate', module: 'hibernate-core', version 'default')
}
on resolution I want this to give me the equivalent of
dependencies {
compile (group: 'org.hibernate', module: 'hibernate-core', version '4.3.0.Beta4')
}
The mapping is specified in a file that contains key/value pairs of something like
org.hibernate.hibernate-core=4.3.0.Beta4
which is read into an extended property of type HashMap on the project called versionMap.
I can get this mapping to work quite happily with the following in my build.gradle file
configurations {
all {
resolutionStrategy {
eachDependency { DependencyResolveDetails details ->
if (details.requested.getVersion() == "default") {
def key = details.requested.getGroup() + "." + details.requested.getName() + ".version.default"
details.useVersion(versionMap.get(key))
}
}
}
}
}
(I need to acknowledge the help of Peter Niederwieser for getting me this far)
As i need the same thing in a number of my projects I want to make this a plugin, so I have created a plugin project and it all build nicely but when I try and run it I cannot access the resolutionStrategy to set the logic. My plugin code looks like this:
import org.gradle.api.Plugin;
import org.gradle.api.Project;
import org.gradle.api.artifacts.DependencyResolveDetails;
import org.gradle.api.artifacts.ConfigurationContainer;
import org.gradle.api.artifacts.ResolutionStrategy;
class DefaultVersionsPlugin implements Plugin<Project> {
@Override
public void apply(Project project) {
def strategy =
{ DependencyResolveDetails details ->
if (details.requested.getVersion() == "default") {
def key = details.requested.getGroup() + "." + details.requested.getName()
details.useVersion(ext.versionMap.get(key))
}
}
ConfigurationContainer configurations = project.getConfigurations();
configurations.each { config ->
println "config: " + config + " - " + config.resolutionStrategy
config.resoultionStrategy.eachDependency{ strategy }
}
}
}
The println above gives valid output but the line following gives an error. The output from running this plugin is.
config: configuration ':alerting:archives' - org.gradle.api.internal.artifacts.ivyservice.resolutionstrategy.DefaultResolutionStrategy_Decorated@e2d0ab
FAILURE: Build failed with an exception.
* Where:
Build file 'C:\trunk\build.gradle' line: 52

Is there any way to set the resolution strategy programatically? I have tried all manner of combinations to setting this but they all give the same error.
I have now fixed this problem by changing the
ConfigurationContainer configurations = project.getConfigurations();
configurations.each { config ->
println "config: " + config + " - " + config.resolutionStrategy
config.resoultionStrategy.eachDependency{ strategy }
}
to
project.getConfigurations().all { config ->
config.resolutionStrategy.eachDependency{ DependencyResolveDetails details ->
if (details.requested.getVersion() == "default") {
def key = details.requested.getGroup() + "." + details.requested.getName() + ".version.default"
details.useVersion(project.ext.versionMap.get(key))
}
}
}
and moving the closure definition inline (not sure if the inline made any impact or not).
