Gradle:通过从属性文件中查找令牌来替换令牌

问题描述

目前我了解到我们可以使用 org.apache.tools.ant.filters.ReplaceTokens 在构建过程中通过以下方式替换文件的内容.

Currently I understand that we can use org.apache.tools.ant.filters.ReplaceTokens to replace the contents of a file during build in the following way.

myBeans.xml:

<bean id="mybean1" class="com.test.MyClass1" >
    <property name="myprop1" value="@myproperty@" />
</bean>

my.properties:

myprop=testme

gradle 文件:

from file("myBeans.xml"), {
   filter(ReplaceTokens, tokens: ["myproperty": project.properties["myprop"]])
}

但是我希望 gradle 从 my.properties 文件中找到属性名称并将其替换到 xml 文件中(在过滤器中没有提到 myprop).如果没有，我将不得不手动添加所有 PlaceHolders.

However I would want gradle to find the property names from my.properties file and replace it in the xml file (without mentioning myprop in the filter). If not, I would have to add all the PlaceHolders manually.

推荐答案

您可以将属性作为映射传递到 ReplaceTokens 配置.密钥必须与您希望看到被替换的令牌相匹配.示例:

you can pass properties as a map to the ReplaceTokens configuration. The key must match the token you want to see replaced. Example:

beans.xml:

<bean id="mybean1" class="com.test.MyClass1" >
    <property name="myprop1" value="@myproperty@" />
</bean>

my.properties:

my.properties:

myproperty=testme

build.gradle:

build.gradle:

task myCopy(type:Copy){
    from "bean.xml"
    into ("$buildDir/beans")
    def myProps = new Properties()
    file("my.properties").withInputStream{
        myProps.load(it);
    }
    filter(org.apache.tools.ant.filters.ReplaceTokens, tokens: myProps)
}

希望有所帮助.
