Looks like there was an error while trying to download web3j source
Issue Description
I am trying to install and use Web3j CLI, but I am encountering multiple issues:
When running:
curl -L get.web3j.io | sh && source ~/.web3j/source.sh
I get the error:
Looks like there was an error while trying to download web3j
source: no such file or directory: /Users/Abhi/.web3j/source.sh
After manually downloading Web3j CLI and attempting to generate code using:
web3j generate solidity \
-a contract/build/X.abi \
-b contract/build/X.bin \
-o contract/generated \
-p com.example.contract
I receive the following error:
Exception in thread "main" java.lang.IllegalArgumentException: version must not be null
at com.github.zafarkhaja.semver.Version$Validators.nonNullOrThrow(Version.java:1383)
at com.github.zafarkhaja.semver.Version$Validators.nonNull(Version.java:1357)
at com.github.zafarkhaja.semver.Version.parse(Version.java:410)
Issue Context
Web3j Version: 1.6.3 OS: macOS Installation Attempted: Both automatic (curl) and manual Expected Behavior: Web3j should install properly and allow code generation Actual Behavior: Installation fails, and code generation throws an error
Would appreciate any guidance on resolving this. 🚀
I have same problem, windows 11 + WSL2(ubuntu 22.04) + jdk 17
problem 1:
curl -L get.web3j.io | sh && source ~/.web3j/source.sh
may should be
curl -L get.web3j.io | bash && source ~/.web3j/source.sh
problem 2:

/home/runner/work/_temp/f34d943d-2129-4bfa-8345-0dde788119f5.sh: line 1: /home/runner/.web3j/source.sh: No such file or directory
Error: Process completed with exit code 1.
At this address : get.web3j.io, we can find the install script.
It contains this block :
install_web3j() {
echo "Downloading Web3j ..."
mkdir -p "$HOME/.web3j"
if [ "$(curl --write-out "%{http_code}" --silent --output /dev/null "https://github.com/hyperledger-web3j/web3j-cli/releases/download/v${web3j_version}/web3j-cli-shadow-${web3j_version}.tar")" -eq 302 ]; then
curl -# -L -o "$HOME/.web3j/web3j-cli-shadow-${web3j_version}.tar" "https://github.com/hyperledger-web3j/web3j-cli/releases/download/v${web3j_version}/web3j-cli-shadow-${web3j_version}.tar"
echo "Installing Web3j..."
echo "https://github.com/hyperledger-web3j/web3j-cli/releases/download/v${web3j_version}/web3j-cli-shadow-${web3j_version}.tar"
tar -xf "$HOME/.web3j/web3j-cli-shadow-${web3j_version}.tar" -C "$HOME/.web3j"
echo "export PATH=\$PATH:$HOME/.web3j" >"$HOME/.web3j/source.sh"
chmod +x "$HOME/.web3j/source.sh"
echo "Removing downloaded archive..."
rm "$HOME/.web3j/web3j-cli-shadow-${web3j_version}.tar"
else
echo "Looks like there was an error while trying to download web3j"
exit 0
fi
}
If I test curl --write-out "%{http_code}" --silent --output /dev/null "https://github.com/hyperledger-web3j/web3j-cli/releases/download/v${web3j_version}/web3j-cli-shadow-${web3j_version}.tar" with version 1.6.2 or 1.6.3, I obtain 301 (Moved Permanently). Script expect 302 (Found)
Until the merge of the fix, you can use this command :
curl -L get.web3j.io | sed 's/hyperledger/LFDT/g' | sh && source ~/.web3j/source.sh
Now fixed : https://github.com/LFDT-web3j/web3j-installer/pull/22. Issue can be closed.
I still see this issue:

We appreciate you reporting this issue! We've attempted to reproduce it on several different machines, but unfortunately, we haven't been able to replicate the error on our end.
Given this, we suspect the problem might be related to your JAVA_HOME environment variable, especially since you mentioned having multiple Java versions installed. Could you please double-check your JAVA_HOME setting to ensure it's pointing to the correct Java installation? Sometimes, having various versions can lead to conflicts or unexpected behavior.
Let us know what you find, and thanks again for your help!
Issue shows up again:
.gradle % web3j --version

@gtebrean I installed version 1.7.0, and I found a situation.
It happens when run web3j in the directory that have file gradle.properties, such as java/kotlin project root.
I ran web3j cli on the root of my kotlin project, and it seems that the web3j-xxx.jar look for gradle.properties in CWD first.
