在build.xml中使用正则表达式

Question

我使用Jenkins构建我的Android Apk。在build.xml中，iam使用正则表达式替换我的目标字符串，如下所示......

<replaceregexp file="BuildConfig.java" 
     match="public static final boolean IS_SAMSUNG_MDM_ENABLED     =\"(.*)\"" 
     replace="public static final boolean   IS_SAMSUNG_MDM_ENABLED  =\"" + ${properties.IS_SAMSUNG_MDM_ENABLED} + "\""  />

但是当我通过jenkins运行构建时出现以下错误。

BUILD FAILED
/var/lib/jenkins/workspace/Ace Build/build.xml:40: The following error occurred while executing   this line:
/var/lib/jenkins/workspace/Ace Build/IgnitorACE/build.xml:70: Element type "replaceregexp" must be followed by either attribute specifications, ">" or "/>".

我的正则表达式有问题......

您获得的错误似乎是因为引号（"）。您应该使用"代替。以下示例有效：

BuildConfig.java：

public class MyFirstJavaProgram {

    public static void main(String []args) {
       public static final boolean IS_SAMSUNG_MDM_ENABLED = false
       System.out.println("Hello World");      
    }
}

file.properties：

IS_SAMSUNG_MDM_ENABLED=true

的build.xml：

<project name="MyProject" default="regextask" basedir=".">
  <property file="file.properties"/>

  <target name="regextask">
        <replaceregexp  file="BuildConfig.java" 
                        match="public static final boolean IS_SAMSUNG_MDM_ENABLED = (.*)" 
                        replace="public static final boolean IS_SAMSUNG_MDM_ENABLED = &quot;${IS_SAMSUNG_MDM_ENABLED}&quot;" 
        />    
  </target>
</project>

输出：

public class MyFirstJavaProgram {

    public static void main(String []args) {
       public static final boolean IS_SAMSUNG_MDM_ENABLED = "true"
       System.out.println("Hello World");
    }
}
