build.gradle中的多行Groovy字符串？

我使用gradle并希望在我的

build.gradle

中创建一个字符串，该字符串跨越多行以使其更具可读性

这是原件：

myConfig {
   myFlags "--no-package-directories --prefixes prefixes.properties -use-arc -classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:${projectDir}/lib/javax.inject-1.jar"

}

我尝试使用groovy多行字符串，但在执行以下操作时，它会引发错误：

myConfig {
   myFlags """--no-package-directories --prefixes prefixes.properties -use-arc 
-classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:
${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:
${projectDir}/lib/javax.inject-1.jar"""

}

编辑：myFlags的定义是：

class SomePluginExtension {
    String myFlags = ""
}

我得到的错误是：

如何在build.gradle中创建多行Groovy字符串？

这是您的原始版本： 以下是我过去为自己所做的努力： 大多数时候，您可以像

Java

一样想到

Groovy

： 有效

Java

：

String var = "--no-package-directories --prefixes prefixes.properties -use-arc " +
       "-classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:${projectDir}/lib/javax.inject-1.jar"

def var = "--no-package-directories --prefixes prefixes.properties -use-arc " +
       "-classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:${projectDir}/lib/javax.inject-1.jar"

有效

Groovy

：

String var = "--no-package-directories --prefixes prefixes.properties -use-arc " +
       "-classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:${projectDir}/lib/javax.inject-1.jar"

def var = "--no-package-directories --prefixes prefixes.properties -use-arc " +
       "-classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:${projectDir}/lib/javax.inject-1.jar"

如果你想发疯： 这对我很有用：

def multyline = '''\
--no-package-directories --prefixes prefixes.properties -use-arc 
-classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:
${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:
${projectDir}/lib/javax.inject-1.jar
'''

---

我希望它能帮助您）

实际上，您的代码看起来是正确的。你能提供myFlags的定义和你得到的错误代码吗？这是编译错误还是运行时错误？@AmnonShochot我更新了我的帖子看起来构建根本没有执行-是真的吗？@AmnonShochot当我在多行中写入字符串时它没有执行。应用程序

Applications/J2Objc/J2Objc-0.9.7b/J2Objc

不管是什么，无法处理位于单独行上的标志。试着在多行字符串的前三行末尾加上“\”，我也试过了，但不起作用。同样的错误。发布您的整个

build.gradle

，我不了解您的错误。

def multyline = '''\
--no-package-directories --prefixes prefixes.properties -use-arc 
-classpath ${projectDir}/lib/dagger-2.0-SNAPSHOT.jar:
${projectDir}/lib/dagger-2.0-SNAPSHOT-sources.jar:
${projectDir}/lib/javax.inject-1.jar
'''
