[jira] Created: (MECLIPSE-427) .springBeans definition throws
NullPointer if BaseDir does not exist
.springBeans definition throws NullPointer if BaseDir does not exist
--------------------------------------------------------------------
Key: MECLIPSE-427
URL: http://jira.codehaus.org/browse/MECLIPSE-427
Project: Maven 2.x Eclipse Plugin
Issue Type: Bug
Components: MyEclipse support
Affects Versions: 2.5.1, 2.5
Reporter: Joe Freeman
This is related to the fix submitted for MECLIPSE-359
We have an application with 40 eclipse projects in it. About half of them have spring beans and 1/2 don't. The top level pom describes how the eclipse plugin should function and includes the Spring configuration component for the myeclipse target. A null pointer is thrown when running eclipse:myeclipse when the base dir doesn't exist, in our case in one of the projects that doesn't have any spring components. Our pom.xml fragment looks like
<spring>
<version>2.0</version>
<file-pattern>*.xml</file-pattern>
<basedir>src/main/resources/conf</basedir>
</spring>
The exception stack trace looks like
java.lang.NullPointerException
at org.apache.maven.plugin.eclipse.writers.myeclipse.MyEclipseSpringBeansWriter.getConfigurationFilesList(MyEclipseSpringBeansWriter.java:142)
at org.apache.maven.plugin.eclipse.writers.myeclipse.MyEclipseSpringBeansWriter.write(MyEclipseSpringBeansWriter.java:93)
The following code block with the problem throws NullPointer when directory.listFiles() returns a null into subdirs. Wrap the for() loop in a nullcheck
try
{
File directory = new File( basedir );
File[] subdirs = directory.listFiles( new FileFilter()
{
public boolean accept( File pathname )
{
return pathname.isDirectory();
}
} );
for ( int i = 0; i < subdirs.length; i++ )
{
configFiles.addAll( getConfigurationFilesList( subdirs[i].getPath(), pattern ) );
}
configFiles.addAll( FileUtils.getFileNames( directory, pattern, null, true ) );
}
Testing:
Take one of the test cases and remove the directory that is pointed to by the basedir attribute.

[jira] Updated: (MECLIPSE-427) .springBeans definition throws

Joe Freeman updated MECLIPSE-427:
---------------------------------
Attachment: MyEclipseSpringBeansWriter.java
This file fixes two problems in our build.
1) It eliminates the null pointer exception that occurs when the build path is pointed to a place that doesn't exist.
2) The spring beans writer only worked if your current working directory was the root of the project that you were building a .springBeans file in. It didn't work if you had multiple, hierarchical, projects where the current working directory stays at the top. The Spring Bean Writer now works for project where it is sitting outside the root of any one code project.
I don't have time to create test cases at this time even though they should be easy.
1) Create a project where the spring basedir for the searching for spring beans doesn't exist. You will get a null pointer exception.
2) Create two hierarchical projects where all the spring files exist in the lower level project. Put the eclipse configuration with <spring></spring> in the top level pom. Then run "mvn eclipse:myeclipse". The .springBeans file will be created but with no spring files listed. Use the patch and you get a .springBeans file with the spring xml files listed in it.
I'm not sure if the path manipulation I did is the approved maven way of fixing this. Another way to fix this would be to have maven cd down into the directory being investigated so that the project root is the current working directory.

The spring definitions file generator should be pulled out of the myeclipse mojo because it doesn't have any MyEclipse dependencies.

This contains the complete test case. I couldn't attach the whole test case as part of the patch file because the svn patch tool won't include empty files in the patch. The test case includes empty placeholder files like the other myeclipse test cases.
