问题 How do I check from within a Mojo if an artifact already exists in the local repository? I'm installing large binaries into the local Maven repository and I need to know if they already exist before attempting to download them. 回答1: Solved with the help of http://docs.codehaus.org/display/MAVENUSER/Mojo+Developer+Cookbook /** * The local maven repository. * * @parameter expression="${localRepository}" * @required * @readonly */ @SuppressWarnings("UWF_UNWRITTEN_FIELD") private

阅读更多关于 Unit Testing Maven Mojo - Components and parameters are null

问题 Based on the documentation and mailing threads I have seen 3 ways to inject the maven project into my mojo: /** * Project instance * * @parameter default-value="${project}" * @required * @readonly */ private MavenProject project; @Component private MavenProject project; @Parameter( expression = "${project}" ) private MavenProject project; But regardless of which one of these I choose, when I run the unit test based on the example I found in maven docs, project is always null. public void

Maven Mojo: Taking complete control over logging / Forbid other plugins to log

阅读更多关于 Maven Mojo: Taking complete control over logging / Forbid other plugins to log

问题 I don't know if this is actually possible, but can I take complete control over logging from inside a Maven Mojo? With complete control I mean that only messages from my Mojo are logged or that I can decide wether a given message shall be logged. The context is that I'm using the maven-scm-plugin in my plugin to do some SCM action and it floods the log with [INFO] Executing: cmd.exe /X /C "svn --non-interactive update D:\..." [INFO] Working directory: D:\... while my own messages get lost and

问题 I want to load most of my scripts in my main layout ( i.e jquery). Now from my understanding it is best practice to position scripts at the bottom of my html page.

Maven Password Encryption for Other Properties

阅读更多关于 Maven Password Encryption for Other Properties

问题 I would like to use Maven's password encryption such as it uses for nodes for properties of a Mojo. I tried just pasting an encrypted password into the correct property for the mojo, but it treated it as plain text. I was hoping there was an attribute I could set on the annotation for the Mojo property that would explain that it could be encrypted, and if so, to use the system master password to decrypt, but I don't see anything in the documentation for that. Has anybody managed to use Maven

阅读更多关于 Maven plugin MOJO API in term of parameters

问题 From my understanding the MOJO relative to the compile goal of the maven-compiler-plugin defines its own parameters,just like any other MOJO plugins. For example it should have a parameter defined somewhat like the following: /** @parameter default-value="${project.build.sourceDirectory}" */ private String sDir; So these parameters definitions represent a kind of API for the MOJO, that we can set in various way, mainly from the execution tag. Please,correct me if I'm wrong. My question is:
