conversion: Filter properties may be specified using groovy map syntax. If you want your replacement to happen based on other conditions, you need to use Gradle's incremental build features to specify that. To handle this case, we have the eachFile() method. SimpleTemplateEngine has some other features that are exposed to you when you use the expand() method inside a copy task. All I was able to find is to parse file through filter during copying it.

The file() method is an effective way to turn paths into files, and the files() method builds on this to build lists of of files that can be managed as collections. This will change the encoding of my file, for example, jsp file. The closure takes a single parameter, which is the name of the original file.

We looked at keyword expansion and line-by-line filtering of file contents during copy, and also at renaming files as theyre copiedsomething that often comes in handy when modifying the contents of copied files. Eventually the MarkdownFilter class could move out of the build entirely and into a custom plug-in. What is the number of ways to spell French word chrysanthme ? If we add the following trivial copy task to Example1-19, well find the lib directory quickly populated with all of the JARs we need after we run the task. Without Gradle we would unpack the archive file, copy our new file into the destination directory of the unpacked archive and archive the directory again. Whatever the reason, Gradle gives you two flexible ways to get the job done: regular expressions and Groovy closures. Well add a task at a time to this example build to see each feature.

We reviewed the three important methods Gradle developers use to deal with files, and finally learned about the all-important FileCollection interface that describes so many important Gradle domain objects. A particular configuration file may contain a substantial set of parameters that do not vary by deployment environment, plus a smaller set of parameters that do.

Any string inside curly braces preceded by a dollar sign (${string}) is a candidate for substitution. Characters with only one possible next character. I already used the replace method and its working flawlessly but once I edit Config.java file manually I could reach some unwanted states, so your solution seems much better. This strategy can be overridden for individual files by using CopySpec.eachFile(org.gradle.api.Action) or CopySpec.filesMatching(java.lang.String, org.gradle.api.Action). Configuration-time build code sets up the task graph for Gradle to process. The given source endings) and should return a String to replace the line or null to remove the line. The Ant API provides a rich set of pre-written FilterReader implementations, which Gradle users are encouraged to re-use. Include calls are exclusive by default; that is, they assume that all files not named in the include pattern should be excluded. If your build has to copy files around, theres a good chance it will have to rename files in the process.

To create a collection of all of the text resources in our example build that are not Shelley poetry, we might add the code in Example1-24 to our build. Immutable data structures have their uses, but in the Gradle lifecycle, this would make file collections difficult to use. in which case the original name will be used.

If includes are not provided, then all files in this container will be included. The task ReplaceRegExp Task - Apache Ant For example, perhaps you have a custom deployment process that copies a directory full of files and accumulates a SHA1 hash of all the file contents, emitting the hash into the destination directory. $property or ${property} in the file. Both can be omitted, if desired. You might use this case if you already had the File object lying around for some reason. Adds an action to be applied to each file as it is about to be copied into its destination. This method may be called multiple times to append new patterns and multiple That might get around the binary and jstl issues that solution has.

You can use the Copy task and ReplaceTokens filter. The variables follow the ${some.property} convention. Example1-22.Using module dependencies as a FileCollection to capture JAR files. Rather than then having another job where I perform changes on the files, then copy them again into the package directory, is there any way to apply changes to the files while they are in motion? Collection elements are recursively resolved, so they may contain any of the other datatypes allowed by files(). Adds an include spec. Indeed the Copy task runs only if the source files changed. The closure should return a String object with a new target name. We can derive a set of examples by using dependency configurations as file collections. Ant-style pattern. If this is undesirable then ContentFilterable.expand(java.util.Map, org.gradle.api.Action) Output file sets are defined on a per-task basis. If you tried running the examples in the the section on the files method and you poked around at them just a little bit, you may have noticed that the return value of the files() and fileTree() methods dont have a very friendly default toString() implementation (Example1-17). The function will be called with a single parameter, the name of the file. Android: How to run asynctask from different class file?
