IWAV0168E Improper nesting of mark statements in Expression. Tried to pop or endMark to before current mark. Tried to go past Mark# 0.

The solution:

1) Open a VE and then close it. Make sure there are NO VE’s open at all.
2) Clear the .log file (use the ErrorLog view and the “Delete Log” button).
3) Projects->Clean…->Clean ALL projects radio button
4) Wait for build to finish
5) Try opening the VE again.

From here, quoted here.

The solution for this error is right here.

annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)

Got this when trying to build a Java 6 application (whose code included annotations) using Maven 2.

To solve it, I added the following to my pom.xml:

<project>
  (...)
  <build>
    (...)
    <plugins>
      (...)
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId> >
        <configuration>
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
      </plugin>
      (...)
    </plugins>
    (...)
  </build>
  (...)
</project>

Getting this error when running Ruby/Rails apps that connect to MySQL 5.1 on Windows?

Copying this DLL to the same directory of ruby.exe (and restarting the Rails app) worked for me.

Using

• Windows Vista
• Ruby 1.8.6
• Rails 2.1.2
• mysql gem 2.7.3
• MySQL 5.1.36-community
