Re: [tycho-user] problem with "Access restriction" from compiler

One question:

the bundle that is accessing this api has a Import-Package to where NamespacePrefixMapper is located ?

Hi list,

I am trying to move from Tycho 0.12.0 to 0.14.0-SNAPSHOT (I need some feature fixed in 14).

My project builds just fine under 0.12.0.

When I use 0.14.0-SNAPSHOT I get the following error from the java compiler:

Access restriction: The type NamespacePrefixMapper is not accessible due to restriction on classpath entry /usr/lib/jvm/java-6-openjdk/jre/lib/rt.jar

Indeed, my source uses NamespacePrefixMapper and indeed that should not be done.

But why does that suddenly break the build? Or maybe I should ask: why did it not break under 0.12.0?

To fix that I tried to put the following in my pom:

<build>
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-compiler-plugin</artifactId>
<ve
rsion>0.14.0-SNAPSHOT</version>
<configuration>
<compilerArgument>
-XDignore.symbol.file=true</compilerArgument>
</c
onfiguration>
</plugin>
</plugins>
</build>


but this does not fix it. I verified that the option is passed to the plugin, the logging shows:

...
[DEBUG]   (f) compileSourceRoots = [.....]
[DEBUG]   (f) compilerArgument = -XDignore.symbol.file=true
[DEBUG]   (f) compilerId = jdt
...

Furthermore I see the following line in the log, which was not there in 0.12.0, does that give a clue:

[DEBUG]   (f) useJDK = SYSTEM

Any ideas?

Thanks,
Tom
