Hello all,
I want to compile a Maven project from Java code. Thus, I am using the
MavenEmbedder (http://maven.apache.org/guides/mini/guide-embedding-m2.html).
Here is my code:
Configuration config = new DefaultConfiguration();
config.setUserSettingsFile(new File("..."));
config.setClassLoader(Thread.currentThread().getContextClassLoader());
ConfigurationValidationResult validationResult =
MavenEmbedder.validateConfiguration(config);
if (validationResult.isValid()) {
try {
MavenEmbedder embedder = new MavenEmbedder(config);
MavenExecutionRequest request = new DefaultMavenExecutionRequest();
request.setBaseDirectory("...");
request.setGoals(Arrays.asList(new String[] { "clean", "install"
}));
MavenExecutionResult result = embedder.execute(request);
if (result.hasExceptions()) {
List<Exception> exceptions = result.getExceptions();
for (Exception e : exceptions) {
e.printStackTrace();
}
}
} catch (MavenEmbedderException e) {
e.printStackTrace();
}
}
When I run this code, I get this log, which show me an error:

Some information:
- I've looked to my local repository, and the plugin
org.apache.maven.plugins:maven-install-plugin:2.2 is present.
- When I execute manually the command "mvn clean install", the project compiles
correctly.
- If I only ask in my code to do the "clean" goal (i.e.
request.setGoals(Arrays.asList(new String[] { "clean" }));), then no error
occurs and the cleaning is done correctly.
What is the problem with my code? How to solve it?
Thanks in advance.
Regards.
