我在这里使用gradle构建几个Eclipse插件： https://travis-ci.org/JPL-IMCE/gov.nasa.jpl.imce.oml.core
这是此回购的CI： https://github.com/JPL-IMCE/gov.nasa.jpl.imce.oml.core
我被这种依赖解析失败困扰了：

使用gradle构建eclipse插件是非常痛苦的，因为解析Eclipse的p2存储库的依赖性是一件很痛苦的事。
由于这个项目使用Xcore，Xtext，Xtend和EMF，我必须添加几个与Eclipse P2 repos相对应的Ivy存储库。
某些P2工件也存在问题，其依赖项包括特定于平台的变量。幸运的是，我设法用替换规则来处理这个问题。
subprojects {
ext.xtextVersion = '2.11.0'
// see http://services.typefox.io/open-source/jenkins/job/xtext-eclipse/job/maintenance_2.11/lastSuccessfulBuild/artifact/build/p2-repository/plugins/
ext.xtextUIVersion = '2.11.1.v20170201-1233'
// see http://services.typefox.io/open-source/jenkins/job/xtext-xtend/job/maintenance_2.11/lastSuccessfulBuild/artifact/build/p2-repository/plugins/
ext.xtendVersion = '2.11.1.v20170201-1447'
// see http://download.eclipse.org/eclipse/updates/4.6/R-4.6.3-201703010400/
ext.emfVersion = '2.11.0.v20160420-0247'
repositories {
jcenter()
mavenCentral()
ivy {

}

}

configurations.all {
exclude group: 'asm'

dependencySubstitution {
// Handle dependency on a variable.
substitute module('org.eclipse.platform:org.eclipse.swt.${osgi.platform}') with module("org.eclipse.platform:org.eclipse.swt.${System.getProperty('osgi.platform')}:3.+")
substitute module('org.eclipse.emf:org.eclipse.emf.ecore.change:[2.5.0,)') with module("org.eclipse.emf:org.eclipse.emf.ecore.change:${emfVersion}")
}
}
}
似乎依赖“org.eclipse.xtext：org.eclipse.xtext.ui：$ {xtextUIVersion}”（即： “org.eclipse.xtext：org.eclipse.xtext.ui：2.11.1.v20170201-1233”）以某种方式让Gradle寻找“org.eclipse.xtend：org.eclipse.xtend.core：1233”
没有这样的版本...... 我试图通过替换来解决这个奇怪的现象。强制规则，这两者都没有帮助纠正这种虚假依赖。
有什么建议吗？
答案 0 :(得分：0)
我附上了一个调试器，看看发生了什么......
export GRADLE_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"
./gradlew :gov.nasa.jpl.imce.oml.dsl.ui:build
然后我在DefaultExternalModuleDependency构造函数上放置了一个断点。当断点命中时：
group: java.lang.String = "org.eclipse.xtend"
name: java.lang.String = "org.eclipse.xtend.core"
version: java.lang.String = "1233"
我看到堆栈跟踪涉及Xtext gradle插件：

查看使用XtendLanguageBasePlugin.automaticallyInferXtendCompilerClasspath的regex version pattern matcher，我发现问题来自该正则表达式：
static val LIB_PATTERN = Pattern.compile("org\\.eclipse\\.xtext\\..*-(\\d.*?).jar")
当应用于“org.eclipse.xtext：org.eclipse.xtext.ui：2.11.1.v20170201-1233”时，它绑定到后缀“1233”。
至少，这解释了虚假依赖的来源。
