database creation failed for apache project log4j

[johninclub]

source code: apache-log4j-2.12.3 download from https://downloads.apache.org/logging/log4j/
os: ubuntu-20.04
maven: Apache Maven 3.6.3
codeql: 2.7.3

I can successfully build log4j without any problems with "mvn package -DskipTests ", but when I tried to create a codeql database with "codeql database create log4j.db -c "mvn package -X -DskipTests", I got the following error messages:

[edoardopirovano]

Greetings! Thanks for reaching out to us with this issue. I note that your command codeql database create log4j.db -c "mvn package -X -DskipTests" is building the CodeQL database inside the same directory that the project is being built in. I've observed this confusing Maven and causing builds to fail before. This may not be what's happening here, but just to rule this out, could I get you to try something like codeql database create ../log4j.db -c "mvn package -X -DskipTests" to place the CodeQL database outside of the project's directory.

If that doesn't resolve your issue, we'll be happy to look into this further for you.

[johninclub]

Thank you for your reply! Got same error when I tried "codeql database create ../log4j.db -c "mvn package -X -DskipTests".

I think this error should be related to the toolchain plugin used in apache log4j. Here is the toolchain config file from apache log4j

As you may see, the first module "Apache Log4j 2" compiled by JDK8 is OK, while the second module "Apache Log4j API Java 9 support" compiled by JDK9 encounters a failure.

Greetings once again, thank you for trying that out for providing this additional information. I've tried to reproduce this issue locally but could not - on my machine, everything seems to work fine. For what it's worth, my toolchains.xml looks like this:

<toolchains>
  <toolchain>
    <type>jdk</type>
    <provides>
      <version>1.8</version>
      <vendor>sun</vendor>
    </provides>
    <configuration>
      <jdkHome>/usr/lib/jvm/java-8-openjdk-amd64</jdkHome>
    </configuration>
  </toolchain>
  <toolchain>
    <type>jdk</type>
    <provides>
      <version>9</version>
      <vendor>sun</vendor>
    </provides>
    <configuration>
      <jdkHome>/home/edoardo/jvms/jdk-9.0.4</jdkHome>
    </configuration>
  </toolchain>
</toolchains>

where the JDK in /usr/lib/jvm/java-8-openjdk-amd64 is the one from the Ubuntu 20.04 package openjdk-8-jdk and the JDK in /home/edoardo/jvms/jdk-9.0.4 was downloaded from https://jdk.java.net/archive/ as Java 9 is out of support and no longer available via the default Ubuntu PPAs (but is required for this build).

The java and javac on my PATH both point to the ones in /usr/lib/jvm/java-8-openjdk-amd64, and I also have the environment variable JAVA_HOME pointing there. The command I ran was codeql database create log4j.db -c "mvn package -X -DskipTests" -l java. Here are logs from my run and the DB produced:

• logs
• database

I'm not quite sure why things aren't working for you, and investigating this further is getting beyond my area of expertise (I work on the general parts of the CodeQL CLI rather than the language-specific extractors). Perhaps someone from @github/codeql-java might be able to suggest what may be going wrong for you.

Thank you for your reply. I followed your setting, and now I can successfully create database. I think the problem might be related to the differences between adoptopenjdk and oracle jdk. The version information of the old jdk9 I used is

openjdk 9.0.4-adoptopenjdk
OpenJDK Runtime Environment (build 9.0.4-adoptopenjdk+12)
Eclipse OpenJ9 VM (build openj9-0.9.0, JRE 9 Linux amd64-64-Bit Compressed References 20180814_248 (JIT enabled, AOT enabled)
OpenJ9   - 24e53631
OMR      - fad6bf6e
JCL      - feec4d2ae based on jdk-9.0.4+12)

The version information of the new jdk9 is

openjdk 9.0.4
OpenJDK Runtime Environment (build 9.0.4+11)
OpenJDK 64-Bit Server VM (build 9.0.4+11, mixed mode)

Interesting, glad it's working for you now and thank you for the additional information. I'll keep this issue open so we can further investigate what was going wrong before once the Java team are back from the holidays.
