Support CDATA section in ConfigurationBuilder

[diablowu]

We need to use the original content of the XML in the plugin configuration buider, but when I use MavenPlugin.ConfigurationBuilder#add(name, xml), the content of xml will be escaped

Thanks for the suggestion, but I am not sure that I understand what you are trying to do from what you have described thus far. Can you please provide an example? Ideally one that shows the code you are using, the output that you expect and the actual output that you currently get.

[diablowu]

For example:

<plugin>
  <groupId>com.diffplug.spotless</groupId>
  <artifactId>spotless-maven-plugin</artifactId>
  <configuration>
    <java>
      <licenseHeader>
        <content></content>
      </licenseHeader>
    </java>
  </configuration>
</plugin>

I want to add the licenseHeader via content . If the content part includes <![CDATA[, then < will be escaped

[diablowu]

And,

build.profiles().id("build").properties().property("maven.build.timestamp.format", "yyyy-MM-dd'T'HH:mm:ss'Z'");

I also want to be able to control the io.spring.initializr.generator.buildsystem.maven.MavenBuildWriter#writeSingleElement to be called without escaping the value part

[wilkinsona]

build.profiles().id("build").properties().property("maven.build.timestamp.format", "yyyy-MM-dd'T'HH:mm:ss'Z'");

How does this relate to inserting CDATA? I'm struggling to see the connection.

[diablowu]

Sorry, this may be another question. But I think this may be due to the method MavenBuildWriter#writeSingleElement without not determining whether the content needs to be encoded

The problem is that something like this doesn't work:

		build.plugins().add("com.diffplug.spotless", "spotless-maven-plugin", (plugin) -> {
			plugin.configuration((configuration) -> {
				configuration.add("java", (java) -> {
					java.add("licenseHeader", (licenseHeader) -> {
						licenseHeader.add("content", """

					});
				});
			});
		});

This creates a XML looking like this:
