Hi @DavidHan008,
These packages require to download Gradle files to build. Your error sounds like a network issue between your computer and the Gradle server. Check if you can download those files at least manually to see if you find the problem.

[DavidHan008]

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip
I solve it thx

[DavidHan008]

@jubeira hi，another problem.
i want to catkin make rosjava_core
but have the same problems
Downloading https://services.gradle.org/distributions/gradle-3.5.1-all.zip

Exception in thread "main" java.lang.RuntimeException: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
at org.gradle.wrapper.ExclusiveFileAccessManager.access(ExclusiveFileAccessManager.java:78)
do you have some idea about download the zip and put it in where?

[DavidHan008]

I can download this zip but I don't know how to manually to use it
can you help me?

[adamantivm]

@DavidHan008 apparently there is a regression on some versions of openjdk 8. See rosjava/rosjava_messages#29

Perhaps you should try switching to another JDK and see if that fixes the issue?

[ericson-cepeda]

To solve it in my case:

1. Download gradle and save it to: gradle/wrapper/.
2. set gradle-wrapper.properties to use the downloaded file.

wget https://services.gradle.org/distributions/gradle-4.1-bin.zip -O "$(pwd)/gradle/wrapper/gradle-4.1-bin.zip"

cat <<EOF > "$(pwd)/gradle/wrapper/gradle-wrapper.properties"
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=gradle-4.1-bin.zip
EOF

Hi David, I am confronting the same issue. How did you get these following lines:
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip

We just found another workaround for this.
OpenJDK-8 or Oracle's JDK 8 don't have this issue. Installing one of those and setting JAVA_HOME environment variable to use it (e.g. export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64) should solve this issue.
For those using Ubuntu 14, check out this link: http://ubuntuhandbook.org/index.php/2015/01/install-openjdk-8-ubuntu-14-04-12-04-lts/. With Ubuntu 16 it shouldn't be necessary to add any ppa repository.
