问题描述

限时删除!!

我的gradle项目使用注释处理器在gen / main / java内部生成一些java代码。当我将这个项目导入Eclipse时,Eclipse不会自动将gen / main / java作为源文件夹添加到构建路径中。我可以手动完成。但有没有一种方法来实现这一点?



谢谢。

解决方案

如果您使用 gradle cleanEclipse eclipse 从命令行生成Eclipse项目,则Andreas的答案有效。如果您使用STS Eclipse Gradle插件,那么您必须在afterEclipseImport 任务中实现。以下是我的完整工作代码片段:

  project.ext {
genSrcDir = projectDir.absolutePath +'/ gen / main / java'
}
compileJava {
options.compilerArgs + = ['-s',project.genSrcDir]
}
compileJava.doFirst {
任务createGenDir<< {
ant.mkdir(dir:project.genSrcDir)
}
createGenDir.execute()
println'createGenDir DONE'
}
eclipse.classpath .file.whenMerged {
classpath - >
def genSrc = new org.gradle.plugins.ide.eclipse.model.SourceFolder('gen / main / java',null)
classpath.entries.add(genSrc)
}
任务afterEclipseImport(描述:项目生成后的后处理,组:IDE){
doLast {
compileJava.execute()
def classpath = new XmlParser()。 parse(file(。classpath))
new Node(classpath,classpathentry,[kind:'src',path:'gen / main / java']);
def writer = new FileWriter(file(。classpath))
def printer = new XmlNodePrinter(new PrintWriter(writer))
printer.setPreserveWhitespace(true)
printer。 print(classpath)
}
}

My gradle project generates some java code inside gen/main/java using annotation processor. When I import this project into Eclipse, Eclipse will not automatically add gen/main/java as source folder to buildpath. I can do it manually. But is there a way to automate this?

Thanks.

解决方案

Andreas' answer works if you generate Eclipse project from command line using gradle cleanEclipse eclipse. If you use STS Eclipse Gradle plugin, then you have to implement afterEclipseImport task. Below is my full working snippet:

project.ext {
  genSrcDir = projectDir.absolutePath + '/gen/main/java'
}
compileJava {
  options.compilerArgs += ['-s', project.genSrcDir]
}
compileJava.doFirst {
  task createGenDir << {
    ant.mkdir(dir: project.genSrcDir)
  }
  createGenDir.execute()
  println 'createGenDir DONE'
}
eclipse.classpath.file.whenMerged {
  classpath - >
    def genSrc = new org.gradle.plugins.ide.eclipse.model.SourceFolder('gen/main/java', null)
  classpath.entries.add(genSrc)
}
task afterEclipseImport(description: "Post processing after project generation", group: "IDE") {
  doLast {
    compileJava.execute()
    def classpath = new XmlParser().parse(file(".classpath"))
    new Node(classpath, "classpathentry", [kind: 'src', path: 'gen/main/java']);
    def writer = new FileWriter(file(".classpath"))
    def printer = new XmlNodePrinter(new PrintWriter(writer))
    printer.setPreserveWhitespace(true)
    printer.print(classpath)
  }
}
