* [maven-plugin] allow for ignore file override
The .swagger-codegen-ignore file is beneficial for existing source
directories to provide pattern-based exclusion rules for existing source
to be ignored by swagger codegen. Until now, there's been no utility
other than skipOverwrite to modify the initial generation of code
(either via CLI or maven plugin).
This commit adds support for an ignoreFileOverride option to both the
CLI and the maven plugin.
Example CLI usage:
```
java -jar swagger-codegen.jar generate \
-i swagger.json -l csharp \
-o target --ignore-file-override /path/to/ignore-file
```
Example Maven Plugin configuration:
```
<build>
<plugins>
<plugin>
<groupId>io.swagger</groupId>
<artifactId>swagger-codegen-maven-plugin</artifactId>
<version>2.2.2-SNAPSHOT</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<inputSpec>${project.basedir}/src/main/resources/swagger.yaml</inputSpec>
<language>csharp</language>
<invokerPackage>io.swagger</invokerPackage>
<modelPackage>io.swagger.models</modelPackage>
<apiPackage>io.swagger.apis</apiPackage>
<ignoreFileOverride>/Users/jim/projects/swagger-codegen/.sample-ignore</ignoreFileOverride>
<configOptions>
</configOptions>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
```
* [maven-plugin] update new javadocs
* fix bad merge due to missing }
* Properly git-ignore all nbactions.xml files.
* Add a command line action to print the program version (#3892).
I am using maven resource filtering capabilities so that an existing version.properties resource file
gets filtered upon build and populated with the project version tag. This resource is then read
at runtime as required.
* Using a different version tag when unreadable.
This implements the command line arguments `--model-name-prefix` and `--model-name-suffix`
for all languages which do not override `DefaultCodegen.toModelName()`.
This fixes most of swagger-api/swagger-codegen#1255.
Connection to the maven plugin works with additional-properties, a more explicit
parameter waits for swagger-api/swagger-codegen#2168.
