将参数传递给gradle中的编译器和javadoc [英] Passing arguments to compiler and javadoc in gradle

问题描述

我试图将Gradle作为现有项目的替代构建系统。该项目使用 sun.misc.Unsafe ，导致如下警告：

 警告：不安全是内部专有API，可能会在未来版本中删除
 import sun.misc.Unsafe; 
  

禁止此警告 -XDignore.symbol.file 作为参数传递给当前ant脚本中的javac和javadoc。

为了在Gradle中抑制这些警告，我必须诉诸于我的感受'肮脏'的黑客，我不太舒服。

  apply插件：'java'
 
 compileJava {
 //我只在设置
 //并将'javac'作为可执行文件传递给
 options.compilerArgs<< '-XDignore.symbol.file'
 options.fork = true 
 options.forkOptions.executable ='javac'
} 
 
 
 javadoc {
 //这些被忽略
 // options.addStringOption（'XDignore.symbol.file'，null）
 // options.addStringOption（'XDignore.symbol.file'）
 
 //这个失败了构建 - 我假设它试图解析''
 // options.addStringOption（'XDignore.symbol.file'）
 
 // This工程，但它是一个丑陋的黑客
 options.addStringOption（'XDignore.symbol.file'，'-quiet'）
} 
  

当然，必须有一种更优雅的方式，我不知道要达到这个目的。

这里（ https://gist.github.com/3772416 ）是一个更完整的示例，其中包含一个伴随的ant脚本和导致该问题的示例类。

谢谢

我正在运行Gradle 1.1

似乎这是一个合理的时间来抑制这些特定的警告。请参阅 - http://forums.gradle.org/gradle/topics/passing_arguments_to_compiler_and_javadoc?rfm=1

解决方案

关于Javadoc，以下方法可能有效：

<$ p $ javadoc.options.jflags-XDignore.symbol.file


关于Java编译，最好知道 options.fork = true 和 options.forkOptions.executable ='javac'（例如1.2）。如果是，请在 http://forums.gradle.org 上提出问题。

I am trying to provide Gradle as an alternative build system on an existing project. That project makes use of sun.misc.Unsafe which leads to warnings like this one:

warning: Unsafe is internal proprietary API and may be removed in a future release
import sun.misc.Unsafe; 

To suppress this warning -XDignore.symbol.file is passed as an argument to javac and javadoc in the current ant script.

In order to suppress these warnings in Gradle I had to resort to what I feel are 'dirty' hacks that I am not too comfortable with.

apply plugin: 'java'

compileJava {
    // I only managed to get this working when I forked 
    // and passed 'javac' as an executable
    options.compilerArgs << '-XDignore.symbol.file'
    options.fork = true
    options.forkOptions.executable = 'javac'
}


javadoc {
    // These get ignored
    // options.addStringOption('XDignore.symbol.file', null)
    // options.addStringOption('XDignore.symbol.file')

    // This one fails the build - I am assuming it's trying to parse ''
    // options.addStringOption('XDignore.symbol.file')

    // This works, but it's an ugly hack
    options.addStringOption('XDignore.symbol.file', '-quiet')
}

Surely there must be a more elegant way that I don't know to achieve this.

Here ( https://gist.github.com/3772416 ) is a more complete example with an accompanying ant script and a sample class that causes the problem.

Thanks

I am running Gradle 1.1

------------------------------------------------------------
Gradle 1.1

Gradle build time: Tuesday, 31 July 2012 13:24:32 o'clock UTC
Groovy: 1.8.6
Ant: Apache Ant(TM) version 1.8.4 compiled on May 22 2012
Ivy: 2.2.0
JVM: 1.7.0_07 (Oracle Corporation 23.3-b01)
OS: Linux 3.2.0-30-generic amd64

It seems that this is a reasonable worakround at the moment for suppressing these particular warnings. See - http://forums.gradle.org/gradle/topics/passing_arguments_to_compiler_and_javadoc?rfm=1

解决方案

Regarding Javadoc, the following might work:

javadoc.options.jflags "-XDignore.symbol.file"

Regarding Java compilation, it would be good to know if options.fork = true and options.forkOptions.executable = 'javac' are still required with recent Gradle versions (e.g. 1.2). If yes, please file a problem at http://forums.gradle.org.
