David Gonzalez commented on SLING-2350:
---------------------------------------
I was able to resolve: java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
by adding slf4j-api and slf4j-log4j12 as plugin depdencies in my pom.xml
<plugin>
<groupId>org.apache.sling</groupId>
<artifactId>maven-jspc-plugin</artifactId>
<version>2.0.6-SNAPSHOT</version>
...
<dependencies>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.5.2</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.2</version>
</dependency>
</dependencies>
</plugin>
I also needed to add a log4j.properties file to the maven-jspc-plugin under
/src/main/resources else i received a numbe of warnings about log4j not being
properly initialized (I couldnt put them in my proj's /src/main/resources, it
had to be in the maven-jspc-plugin project's).
I am now running into a NullPointerException:
ava.lang.NullPointerException
at
org.apache.sling.scripting.jsp.jasper.compiler.Compiler.isOutDated(Compiler.java:361)
at org.apache.sling.maven.jspc.JspcMojo.processFile(JspcMojo.java:359)
at
org.apache.sling.maven.jspc.JspcMojo.executeInternal(JspcMojo.java:315)
at org.apache.sling.maven.jspc.JspcMojo.execute(JspcMojo.java:227)
I've included the entire maven build output here:
https://gist.github.com/1592959
It looks like in Compiler.java its throwing the exception because jsw is null:
final long lastModifiedTest = jsw.getLastModificationTest();
In JspMojo,processFile the Compiler object is created, however i *think* the
only way to set the JspServletWrapper in the Compiler is by calling its:
public void init(JspCompilationContext ctxt, JspServletWrapper jsw)
And it's not, thus its null.
I looked through code and im not sure I understand what would be needed to
create a JspServletWrapper obj properly, or if its even needed (is
jsw.getLastModificationTest even truly needed?)
Any thoughts around this?

> Buiding Sling-based project using the Maven JSPC Plugin but am getting
> compilation errors because SlingHttpServletRequest object doesn't have
> .adaptTo(...) defined.
> Latest Sling API docs state:
> Starting with Sling API 2.0.6, this [SlingHttpServletRequest] interface
> also extends the Adaptable interface.
> Sling Maven JSPC Plugin 2.0.4-incubator plugin [1] depends on "Sling
> Scripting 2.0.2-incubator" [2] which in turn depends on "Sling API
> 2.0.2-incubator" which is older than 2.0.6 thus no Adaptable support.
